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

+I finally did something towards a useful interactive email interface
+;).  As per our new guidelines, I'll develop this feature in it's own
+branch:
+  http://www.physics.drexel.edu/~wking/code/bzr/be-email
+
+The interface is basically "place your be command in the subject line"
+with a few exceptions.  Some examples:
+  Subject: [be-bug] list --status=all
+  Subject: [be-bug] show --xml ID
+  Subject: [be-bug] new
+  Subject: [be-bug] comment ID
+In the case of "new", the bug description is extracted from the first
+non-blank body line.  In the case of "comment", the email body is used
+as the comment.  Currently only "list", "show", "new", and "comment"
+are allowed.
+
+You should get a reply email with exit status, stdout, and stderr from
+your command.
+
+Send some mail to [wking (at) tremily (dot) us] to try it out!  Depending
+on spam attraction, this might be a limited time offer ;).
+
+Hopefully this lowers the entry barrier for bug reporting :).
+
+Disclaimer: I imaging the current implementation will choke on
+non-text/plain content types.  Also possibly on non-ascii encodings.
+Probably lots of other bugs too... ;).  For example, I should probably
+allow the "help" command ... ;).
+
+Cheers,
+Trevor
