It got denied before for Software so I won't include it in the merge request :(

In theory, should be a performance improvement. In practice idk

I heard properpaper had some weird crashes? I couldn't reproduce
them no matter how hard I tried, but I added some bounds checking
to this version too just in case. Gotta get other people's help
to try to reproduce those.

* Break bustable FOFs like pushables.
* Activate pushable-counting executor activators.
* Get pushed by currents/wind.

This takes advantage of the previously-existing hack relating to objects with MF_PUSHABLE infotable (but not active) flags and a nonzero fuse, which is used as the condition to group this under (rather than MT_ROLLOUTROCK specific fuckery).

Thanks to the bug report submitted by our kirbs pal for getting me off my ass this evening.
