Fix issue #435, and also unreported bug when 2 or even 4 entries could have selection at the same time in weapons menu.

these files had the executable flag/permission set

issue #443 - change in syntax for effects

minor macro cleanup

updated italian translation (#447)

Clear hedgehog's gear Power value when switching. Should fix issue #446 (not tested, but looks obvious).

Oops, fix room players list emptyness

This should cover all entries from issue #438

Fix cake splashing bug (issue #429)

No hacks! Fix issue #437

fix for issue #441 ("Cannot overwrite default weapon set 'Default'!" message when no change to weapon set was made)

Set minimums on a few values to avoid camera zooming out past them. partly issue #430. Might be worth defining a new constant for this.

eh. might as well toss this in for reference purposes
