regexp triggers

[odbrazen]

We need a simple one-line way to add triggers. This is possible now, [see basiccommands.ReMatchTrig] but not full featured. One possibility is cribbing the syntax from lyntin. Another is populating the interactive interpreter namespace with helper functions (I like this solution better) eg/
  @add_trig('^\w falls down dead', 'loot corpse')
would expand to
  def add_trig(re_text, send_text):
    sess = engine.sessions[0] # current session
    trig = catcher.REMatch(re_text, listen=1)
    def send_text(dummy):
      sess.to_mud(send_text + "\n")
    trig.add_callback(send_text)
    sess.icatch(trig) # add the catcher to the incoming text stream

Since commands starting with '@' use the python interactive interpreter we wouldn't have to do any parsing by hand. Also, the syntax is familiar to anyone that knows python (and/or it teaches python to people who don't know it).

to add a trigger
@trigger('your regexp here', 'this gets executed as if typed in the entry box', listen=1, no_ansi=True)
the options are passed to the catcher.REMatch.__init__ so for one-shot triggers include count=1, for muffles use muffle=True, etc

added the '#triggers ' command which can be used to list/delete triggers created with the @trigger command.
