update qtpropertybrowser source download away from Nokia in Ubuntu build script. Now to some old random mirror of trolltech ftp, was the only place i could find with some googling now (didn't find qtsolution in qt-project.org etc)
fix Python module build after TundraCore refactor, just remove the ogre ECs from the linked libs list. Thanks to Peter/th3flyboy for the fix originally! (in pullreq #603 but that has other things bundled too)
oops fix a typo in previous, failed to test properly as didn't remember that cmake checks py usage from an env var nowadays too
