Port of -tg-'s port of /vg/'s asset cache
Funny thing is, this actually replaces an old version of /vg/'s asset
cache we already had
IT'S A PORT OF A PORT REPLACING A PORT
POOOOOOOOOOOOOORTCEPTION
Basically, gets rid of the 30-40 second interface lag when you first join,
via *mumblemumble* MAGIC!
Also moves a few nano files around.
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.
