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

+Example:
+
+We're working happily in a versioned bugdir, and our RCS knows who we
+are.  We create a temporary repository copy from a previous revision
+for diff generation.  We set the RCS for the copy to "None", since we
+didn't bother initializing our normal RCS in the snapshot copy.  But
+now the BugDir instantized on the copy doesn't know who we are!
+
+Solution:
+
+Track user id in the bugdir settings file.  If you
+bugdir.settings["user_id"], it will be saved and loaded.  When loaded,
+it will also set bugdir.user_id.  If you set rcs.user_id, it will be
+returned by rcs.get_user_id(), instead of returing the output of
+rcs._rcs_get_user_id().  We should be caching the output of
+_rcs_get_user_id() anyway.
