Merged be.restructure, major internal reorganization.

Added a bunch of classes to make the commands, user interfaces, and
storage backends more abstract and distinct.  This should make it much
easier to extend and maintain BE.

Features:
 * Directory restructured:
   becommands/ -> libbe/commands
   submods sorted by functionality.
 * Lots of new classes:
   Option, Argument, Command
   InputOutput, StorageCallbacks, UserInterface
   Storage
 * Consolidated ID handling in libbe.util.id
 * Transitioned VCS backends for Python-based VCSs from subprocess
   calss to internal python calls.

Plus the user-visible changes:
 * New bugdir/bug/comment ID format replaces old bug:comment format.
 * Deprecated support for `be diff` on Arch and Darcs <= 2.3.1.  A new
   backend abstraction (Storage) makes the former implementation
   ungainly.
 * Improved command completion.
 * Removed commands close, open, email_bugs, 
 * Flipped some arguments
   `be assign BUG-ID [ASSIGNEE]` -> `be status ASSIGNED BUG-ID ...`
   `be severity BUG-ID SEVERITY` -> `be severity SEVERITY BUG-ID ...`
   `be status BUG-ID STATUS` -> `be status STATUS BUG-ID ...`

In the merge:
  * Added 'commit' to list of pagerless commands.
  * Updated doc/README.dev

difficulties en-route.
