[CMake] FindGit.cmake on Windows

[Dixon, Shane]

Is it possible to update the FindGit.cmake module to be more friendly?  I changed the line:

find_program(GIT_EXECUTABLE
  NAMES ${git_names}
  DOC "git command line client"
  )

To:

find_program(GIT_EXECUTABLE
  NAMES ${git_names}
  PATHS "$ENV{ProgramFiles}/Git/bin"
  DOC "git command line client"
  )

And it found Git fine on my system.  I'm not sure if that's the only path that ought to be added, but I know that worked for me.
