[pitivi] Refactor the pitivi-git-environment script to be smarter

    Refactor the pitivi-git-environment script to be smarter
    
    It now has a proper --build parameter that automatically
    handles missing directories (allows resuming the build),
    and the shell environment now has a working custom look.
