  queue operations, which causes an automatic deadlock on
  a: get
  a: ... lock _queue_lock
  a: ... block on _queue
                          b: put
                          b: ... block on _queue_lock
  Because nobody reads from the main queue that used round = True, this
  doesn't change application behavior.
* Drop return value of Reports.put, it is always None anyway.
* Fix self._mailboxes locking: instead of
      try:
          lock
          ...
      finally:
          unlock
  it needs to be
      lock
      try:
          ...
      finally:
          unlock

    1. <flow> with the -f function is optional.

    1. Make the usage message more readable.
       It now prints "firstaidkit" as opposed to the caller string.  This
       allows the description to go into the next line without loosing
       prettiness.
    2. Make usage more compact.
       Compact the explination of "-a" into one item in the usage string.

It is possible for the plugin name to have a space.  when this
occured it threw off the argument detecting logic.  This new
way of detecting the plugin name is more general.

Given that firstaidkit is fully automated we need a way to modify the
plugin behaviour from the initial command.  This makes it easy for the
plugin developer to get a string with some arguments for his plugin.
It is up to the plugin developer to parse the string.
The arguments will be accessible through self._args variable.

If it is not placed in the same line it will look distorted.
