Performance enhancement. In order to save on the time it takes to

parse and generate the plain text message each time it's enqueued or
dequeued, we now use a binary cpickle as the message representation
file.  This is controlled by a module global SAVE_MSGS_AS_PICKLES
which defaults to 1.  When a message is saved as a pickle, its
extension will be .pck instead of .msg.  dequeuing will automatically
recognize the different message formats and load accordingly.

Specific changes include:

enqueue(): If SAVE_MSGS_AS_PICKLES is set and the message metadata
does not have a "_plaintext" key, then the message object is stored as
a binary cpickle dump for speed.  The incoming scripts post, join,
leave, etc. will set the _plaintext key because they funnel the text
straight from stdin to the .msg file, and the message text is only
parsed on the first dequeue from qfiles/in.

dequeue(): First try to load and unpickle the .pck file, falling back
to loading and parsing the .msg text file if the former is missing.
