Version 0.6.0rc2 released.

This version includes some bugfixes.

Most important changes since 0.6.0rc1:

* Fix for relative paths to the mplayer binary. The problem could cause that smplayer couldn't play anything if a directory or file named "mplayer" existed in the home directory.
* The option Play -> Repeat has been improved.
* The selection of chapters in mkv files didn't work well if using a recent mplayer from svn. This has been fixed now.
* (Windows) Bugfix: the buttons to select the font color in Preferences->Subtitles->SSA/ASS didn't show the color.
* (Windows) Now the screensaver should be disabled even if protected by password (tested on Windows XP).
* (Windows) Bugfix: don't try to convert to 8.3 short names files that don't exist. That could cause that URLs were corrupted.
