Update AUTHORS, LICENSE and README.md.
Update .gitignore.
Add buildScripts, add an installer for Windows and Linux.

Windows: NSIS, see: http://nsis.sourceforge.net/Main_Page
Linux: makeself, see: http://megastep.org/makeself/

on a debian like linux install the following packages:
$ apt-get install makeself nsis

Also get the latest version of mono for the Windows installer:
See: http://simendsjo.me/files/abothe/
$ wget http://simendsjo.me/files/abothe/MonoDevelop.x64.Master.tar.xz
$ sudo tar xf MonoDevelop.x64.Master.tar.xz -C /

Now you can do:
$ ./buildScripts/make-gtk.sh Release
$ ./buildScripts/make-winforms.sh Release

The resulting installers are in installer/Gtk|Winforms/
Remove old Splashscreen code, which doesn't compile.
