[Feature] Opening Crates and Lockers Sets off Armed Mousetraps Inside

[AlfredoChicken]

What the title says. Opening a crate or locker by hand will set off any armed mousetraps/mousetrap assemblies. Pie traps will target the user that opened the storage object. 

Use it to pie you friends, blow up your enemies, or bolt greedy staff assistants into small rooms.

This is my first patch, so if something is horrendously wrong, that's my excuse.
