Experimentally add a rule to re-run Repoint if the project or lock file is newer than the .repoint.point file. This sort of thing isn't sufficient for all uses of Repoint because some of the initial qmake project file info is brought in by Repoint, so it has to be run before qmake as well. Also it's not clear yet how it will interact with archived builds (i.e. source releases) -- to be tested.
