QoL update for janitors.

[Glamurio]

while you're at it you can put a bunch of tools in it too, spray bottle sponge and stuff so they don't have to do the roundstart item grabbing, just my personal preference and a dev would have more solid input for you

The janny pack right now includes the janitor towel, handheld vacuum, sponge and spray bottle. They also now spawn with a mop in hand and a bucket in their bag. Didn't want to give them too much stuff, felt like that's a nice array of utensils, stuff like garbage bags and cleaner grenades are easy enough to purchase.
