Cleaned trailing whitespaces, as suggested by  Shlomi Fish (bug #702273)
Fixed formatting configuration.
Add support for webm and ogv video file extensions, based on a patch from Shlomi Fish (bug #702273)
Regex optimized not to use named groups (and only captures the end of the filename now, not the whole filename)
When the application is run with a subtitle file as first arg, validate that arg appropriately and convert it to absolute path if necessary (fixes #702413).
Don't delete the gnome-subtitles script - it's generated in "configure", not in "make". This made "make" fail after a "make clean" (which would remove the script).
Set the gstreamer library as a dependency (this way it's required to be compiled in order to be copied). Related to bug #702271.
