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.
