FMod - Bio Menace Tileinfo

As I noted yesterday, Bio Menace stores the background tileinfo data (animation offset and delay) in the reverse order of that used in Keen Galaxy. Today I added a project file setting and a static field in BackgroundAnimHelper to account for that. Bio Menace background tileinfo can now be edited using the normal animation tools in the Tile Property Modifier.

I also made the generic (pre-v2.7) tileinfo list be copied into the per-project tile property lists if the project file was not built from a template. That way, no inconvenience is had when upgrading to v2.7, but all the benefits - adding custom named properties - are accessible.

A little more testing, especially of that last part, has to be done, but I'm just about ready to release Abiathar v2.7!
