wxInterface Testing: 0.3.1 released!

Following the Linux Kernel release system, I'm starting 0.3.x release cycle. These versions are testing releases, more like development snapshots. There is no guarantee they will compile, they might behave unexpectedly, burn your dog or insult your CPU, so proceed on your own risk. Also - these are source-only releases - this is to save my time (making full binary-release takes ~6 hours) and avoid dumb-users using testing versions. Compilation instructions for all platforms will be posted to forums shortly.

Starting the wxInterface-Testing release cycle, this version brings flat-look on win32 (by patching wxWindows library with mswflatbuttons.patch - apply at top level with patch -p0 mswflatbuttons.patch) and brand new search page. Also fixed minor memory leak in list column hiding context menu creation and added Mac .app generation script by Julien Palmas.
