- added a pseudo-serializer for FLevelLocals pointers.

This doesn't really write out any info for the pointer, if the level does not match it just errors out.
This is both for quick detection of badly used level data and for automatic restoring of the pointer from the serializer's working level.

This also removed the temporary workarounds in DAutomap and DLevelScript to restore these pointers when a savegame is loaded.
