VirtMus full changelog

The ability to attach tags to songs and playlists, and to view the songs and playlists belonging to a tag.
Added statistics collection/logging.
Prevent the screen saver from starting while playing.

Features added:
· Better support for Windows 7
· When closing the application, the user now has the choice of saving some or all of the modified contents.
· PlayLists can now be tagged (from the quot;Propertiesquot; window)
· New toolbar button allows the user to quickly toggle the scrolling amount from 100% (a full page) to 50% (half a page at a time). This comes in handy when one image contains two music pages side-by-side (ex. when copied from a book). Toggling the scroll amount to 50% results in music pages being scrolled one at a time instead of two at a time.
· A secondary PDF renderer was added and is now being used for some types of PDF files that used to show gibberish with the original renderer.

Improvements or bugs fixed:
· Better handling when the music repository is moved to a different drive or different location on the same drive.
· Upgraded to NetBeans 7.1.2
· Upgraded some of the external libraries used by VirtMus

Features added:
· Added the ability to undo annotations.
· A double-click, or a right-click on the thumbnails now displays them in the annotation window.
· Multi-threaded some operations to speed things up.

Improvements or bugs fixed:
· PDFs that have different resolutions in the X and Y direction are now handled properly.
· Improved the display of help in Linux.
· Fixed rendering of rotated PDF pages.
