API Improvements

[operand]

This issue is about making a number of API and internal improvements. Rather than create issues for each I'm listing them together here. Most of these are relatively small and could be fixed together. Some of them will be breaking API changes so it makes sense to try to bundle some before the next version increment.

If you have thoughts on these or other API improvements you'd like to see please share.

• Remove "id queue" declarations in AMQPSpace
  Instead use ack/timeouts to return a "not found" error. It wastes resources on the server and isn't foolproof anyway.
• Move thread event declarations out of Agent class
  This would keep all the threading details in the Space class making the Agent class more portable
• Remove colorama dependency
• Wider Python support including MicroPython
• Broadcasts should be self-received
  This was a hasty choice made early on and I just haven't gotten around to changing it. The current pattern is not the standard way that a broadcast is handled. The API shouldn't be surprising like this.

most of this was addressed with 1.3 so I'm closing this issue. I'll make a new issue for wider python support.
