Modified app_queue.c and chan_agent.c 

DETAILS:

* added a strategy called skillbased that does a bitmask compare similar
  to chmod

* added the ability to provide a skillmask to a call from the Queue application
  so it can be matched against the skillmask of the agent

* added a toolong arg to Queue that lets a call fall to the next item
  in the dialplan after x seconds.

* modified chan_agent to have an a flag so you can log in with no
  password

* added configration changes to queues.conf allowing you to setup
  chime-in sound files to tell the customer to stay on the line etc
  and a special keyword announce_pos that provides allison's voice
  telling you where you are in the queue and how long you need to
  wait.  This announcement can be mixed and matched with real sound files.

* fixes to chan_agent eliminating some deadlock scenerios
  (thanks tholo)
