Several fixes to make RabbitMQ a player.

  * extlib/Stomp.php
    -spaces for tabs (we're on PEAR, right?)
    - send: initialize the $properties parameter as array() instead of null
      this prevents unsetting $headers if $properties was not set
      (besides that, it's the proper way to initialize an array)
    - subscribe: insert FIXME's on ActiveMQ specifics
    - ack: make sure the content-length header is set *and* is zero.
      I have seen the header set to '3' there but could not find where it
      came from, this is at least safe.
    - disconnect: typo in $headers variable
    - readFrame: use fgets() instead of gets() so that RabbitQ, which is more protocol strict can also play
  * extlib/Stomp/Frame.php
    - spaces for tabs
    - add note on possibly protocol violating linefeed
  * extlib/Stomp/Message.php
    - space for tabs
    - add content-length header for message
  * lib/stompqueuemanager.php
    - use the notice for logging, not the frame
