This commit does the following:
- Ports progress bars from -tg- (tgstation/-tg-station#9921)
- Refactors wall attackby code to make it 100% less insane; Instead of
manually checking every little thing, it uses do_after,
consequentially, making the new progress bars affect dealing with walls
as well.
Wall code makes a tiger sad.
Restructures the ninja files into a more spaced-out version, compliments
of /TG/. The energy katana is also their handiwork.
Add an emag act to crates and lockers instead of handling everything in
attackby.
