* uninstaller: delete zlib1.dll (first issue in #876)
* require the user to uninstall the old version before installing the
new one
* use project-version as branding name (fourth issue in #876)
Remove argument that if added by default with out having the proper configuration defined during compiling would cause cockatrice to not open properly.
* Move all cmake-related files in a new “cmake” folder
* move nsis files in there, too, since they are templates parsed by cake
* retrieve git version once when cmake is run, and use it for both
creating version_string.h/cpp and for package naming
