Clean up Import Statements.

Allowed Eclipse to auto-clean imports.
Background Connection

Connection object is now created
in a background thread in case RPM is offline.
Use:

while rpm.conn is None:
  sleep(1)

to wait for connection to come online.
Better Doc Strs.

Doc Strings for dynamic functions now indicate that
they are keyword mappings (not just valid keywords) ->
their intention is to map valid python keywords to
JSON Objects that wouldn't be valid as function
arguments.
Clean up write method / debug output.

The Write Method on Telnet doubles IAC control characters
(\xff) which is unnecessary on this client.  Also, better
use of the built in debug output from the Telnet Class.
