Make profiling commands

[coyotte508]

Server crashed, restarted.

Anyway we now have profiling commands.

Add /profiling and /clearprofiling command.

/profiling should do something with sys.profileDump(). (split it with \n, send each message to the player for example)

/clearprofiling should do sys.resetProfiling()

Wriggle did these forever ago, I think. So closing
