installers

PR to finish the installers for libGitWrap.

:question: @scunz The "UloadPPA.cmake" module should move to RAD-Tools, shouldn't it.

- [x] Create a PPA on Launchpad ( https://launchpad.net/~nilsfenner/+archive/ubuntu/macgitver-dev )
To add the PPA write this in a terminal `sudo apt-add-repository ppa:nilsfenner/macgitver-dev`

- [x] (Need to talk about the PGP signing etc.) Generate Debian source package for uploading to the PPA.
- [x] Create DEB install package
- [ ] Create an RPM installer for Suse/Redhat distro's.
- [ ] Finish the OSX DragNDrop Installer (Sascha, could you do that?)
- [ ] Finish the NSIS based installer for Windows

@jakro00 Would be great, if you could help out by fixing the Windows build and then create the NSIS installer in `CMakeLists.txt`. To do so, clone this repo and create a topic branch on `development` with your initials in front (for example `ck/windows-build`). Please write me a message and you will access for direct push to Github - no fork needed.
