Mapgen: Remove unused 'flat' and 'trees' flags from mg_flags
When the 'flat' and 'trees' flags were moved into mgv6_spflags they were left in mg_flags in an attempt to support old mgv6 worlds. However their appearence in mg_flags causes confusion, also, later, old-world support was found to be broken for mgv6 worlds with 'notrees'. This commit cleans up the mess and comes a month after a thread warning of the change, and explaining the required action, was posted in the news subforum. Only old mgv6 worlds with 'flat' or 'notrees' are affected, a small minority of worlds, the required action being correctly setting these flags in mgv6_spflags. Disable a section of the 'map settings manager' unit test which is to be changed as it is causing problems for pull requests.
