Cmake overhaul

Protobuf depends on pthread under unix, but cmake’s FindProtobuf
doesn’t add -lpthread to link flags

Additional: remove duplicate if(linux) and merge rules together

* Use automoc instead of a manual list of headers
* Remove Qt4 detection
* Created missing .cpp for .h files (for automoc detection)
* Remove pthread linking
* Forcing -lprotobuf is not needed for mingw; msvc only?

* Remove cockatrice_HEADERS (obsoleted by automoc)
* Remove compilation flags definition and Qt4 finding calls
* Make use of CMAKE_INSTALL_PREFIX
* use INSTALL(TARGETS) in place of INSTALL(PROGRAM)
* Osx: create a proper application bundle
* Added comments
