Major cleanup

Added cmake.h and cmake.cc to handle parsing of CMakeLists.txt files. Also fixed compile, and compile and run. Quite a few files changed, thus the pull request.

Should find the cmake-root as well as project name in most conditions, and the executables (although, only the first one is selected in window.cc at this point). Be aware that running juci twice in Debian Stable using Gnome does not work for some reason, though other applications can be run through Juci without problem in Debian Stable.)

Remember to delete ~/.juci/config/config.json before testing.

Going to add a way to stop the running application in the terminal at some point.
