FET full changelog

Corrected some non-critical bugs, reported by Volker Dirr, who found them using ChatGPT.
Minor code corrections (reported by Volker Dirr, who found them using Coverity Scan).
The HTML timetables will no longer contain an empty header cell or title, if the names, long names, and possibly codes are all disabled by the user for that category, but they will contain the names, instead (suggested by Vangelis Karafillidis).
Improved the program icon (suggested by Michael Towers, who reported that the previous icons were not correctly visible with a dark color scheme; the new colors were chosen by Michael Towers, Rodica Lalescu, and Liviu Lalescu).
Added a new example file, for the Mornings-Afternoons mode, by Benahmed Abdelkrim.

When generating multiple timetables, there is now an additional report file which lists the timetables in ascending order of conflicts (suggested by Frank Rump).

Corrected and improved the instructions for the new constraints of type room(s) max activities per teacher and building(s) min one activity in each available slot.
Corrected the Arabic translation, by Benahmed Abdelkrim.
Updated the Brazilian Portuguese translation, by Alexandre R. Soares.
Updated the Italian translation, by Andrea Primiani.

Converted the constraints of type building(s) min one activity in each non-break time slot to the similar constraints of type building(s) min one activity in each available time slot (suggested by Benahmed Abdelkrim). Also, these constraints must no longer be applied to all the buildings, but can be applied to any selection of buildings (again, suggested by Benahmed Abdelkrim).
Added some tests before the generation, if the timetable is impossible because of the constraints of type building(s) min one activity in each available time slot (suggested by Benahmed Abdelkrim).
Minor code improvements.
Corrected the Arabic translation, by Benahmed Abdelkrim.

Updated to Qt 6.11.0.
Converted the recently introduced constraints of type room(s) max teachers repetitions to the constraints of type room(s) max activities per teacher (suggested by Andrea Primiani). The new constraint is clearer, and it is equivalent to the old one if we add 1 to the number of max repetitions per teacher to represent the number of max activities per teacher. Also, activities with several teachers are taken into consideration.
The export of statistics can now be configured to use long names and/or codes for the subjects, activity tags, teachers, and students (suggested by Cyrus Ireri).
Updated the Italian translation, by Andrea Primiani.

Added two new constraint types, for exams in Algeria, Morocco, and maybe other countries: room(s) max teachers repetitions and building(s) min one activity in each non-break time slot. These constraints were suggested and tested by Benahmed Abdelkrim (previously in the FET-NSRT custom version) and have some preconditions (listed in their dialogs) to be used successfully.
Added the options to select whether to print the names and/or long names of the days/hours and names and/or long names and/or codes of the teachers in the teachers' free periods timetables and names and/or long names and/or codes of the teachers/students in the teachers'/students' statistics timetables (suggested by Cyrus Ireri).
Added the option to have long names on multiple lines for the days, real days, hours, real hours, subjects, activity tags, teachers, students sets, buildings, and rooms (suggested by Cyrus Ireri). In this way, you can split the long names on multiple lines in the resulted timetables.
It is now possible to have the institution name on multiple lines.
The option to print detailed teachers' free periods timetables was changed: if selected, the behavior is the same as in the older versions, but, if not selected, the program will print all the free teachers in each corresponding time slot, but without printing any additional information, and in the global order of the teachers (suggested by Cyrus Ireri, and maybe other users in the past).
Minor interface bug fixes and improvements (an aesthetic improvement was suggested by Rodica Lalescu, in the 'Space' shortcuts tab).

Critical crash bugs fixed in the students groups/subgroups dialogs (following the report by miky).

Critical crash bugs fixed in the students groups/subgroups dialogs, if the "Colors" check boxes were selected (reported by miky).
Minor corrections and improvements.

Added three new types of space constraints: room(s) pair of mutually exclusive time slots, room(s) pair of mutually exclusive sets of time slots, and room(s) occupy(ies) max sets of time slots from selection (suggested by Rodolfo Ribeiro Gomes). On this occasion, there were added the general constraints (for all rooms, not only for a single room, as in the previous versions) of type rooms max activity tags per day/real day/week.
Minor bug fixes and improvements.

Corrected a few compilation warnings when using an older C++ compiler.
Updated the Italian translation, by Andrea Primiani.
Minor improvements.
