QtGrace full changelog

This release v0.2.6 contains several additions especially concerning the user interface. I tried to fit the changes in while keeping as much of the Grace-interface unchanged as possible. In some cases I used switches in the preferences where the user can activate or deactivate new features in some other cases I just added new options or had to do some minor rearrangements. I hope this is not too much of an inconvenience to anybody.
There are most probably still a few bugs present.

· This release contains only some minor bug fixes and a few improvements.

· I added a 'Fit'-button below the page-zoom-slider to adjust the page-size to fit the window-size.

· I added options for selecting sets with odd or even set-ids in the set lists and an option to select and copy odd or even lines in the spreadsheet-editor. The print-command (like 'lpr') is now saved in the users preferences file (qtGrace_Settings.ini) for users who do not use lpr or who want to use more complicated commands with options regularly.

· I also tried to improve the support for non-ascii-characters in file-names and file-paths. I tested it a bit and it seems to work, but feedback on this is always welcome.

· Only small changes in ps-driver and in the determination of the file-path and file-extension for the print-setup-dialog (now the complete path is always used for print-to-file).
· Changes in 0.2.2: I reactivated the '-free' option at startup. Somehow I forgot to reactivate this feature during my initial development phase. (By the way: Using this option will deactivated the page-zoom-slider.)
· Changes in the last version involuntarily but effectively deactivated the Immediate-update feature.
· I removed this bug (Immediate-update should work again.).
· In previous version the string-justification-selector often returned invalid justification ids.
· I changed this: The string justifications are now as they should be (i.e. if you give a viewport-coordinate for placing a string then this coordinate will be at the point indicated by the justification selector icon in relation to the whole strings bounding box).
· I added a key-shortcut: quot;Crtl+1quot; will reset the page-zoom-slider to '1.0'.
