Enabled friends module, added friends check in imbusy, fixed small mistakes

I used reflection to get the Map<String, Command> object from the SimpleCommandMap instance stored in the implementation of PluginManager.
I replaced all Command instances in there that handle /msg, /tpa, /tpahere and /reply, minus /minecraft:tell, with a wrapper that checks if the target is busy.
Tested adequately, but some more would be nice.
