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 don't think we ever rever to GNU RCS.  Our current libbe.rcs.RCS
+default implementation is a "don't version" backend for BE, but
+perhaps this is what you're refereing to.

+
+Hmm, we really need a method for upgrading the on-disk BugDir version.
+It's hard when you need to maintain backwards compatibilty with
+earlier versions in the VCS history....

+Howdy all,
+
+Currently, the code and interface of Bugs Everywhere speaks loosely
+about the term “RCS”. Sometimes it means “revision control system”
+referring in general to these types of system, and sometimes it talks
+about GNU RCS, a specific system.
+
+I propose that “Version Control System” (“VCS”) has emerged as a
+consensus term to refer to such systems in general, with no specific
+reference to any particular system.
+
+So I'd like to modify the Bugs Everywhere code to disambiguate: the term
+“VCS” will be used consistently to refer to version control systems in
+general, and “RCS” will only ever refer to GNU RCS.
+
+This will change some interface (e.g. the ‘rcs_name’ configuration
+setting, and some of the methods on objects), but making this change
+while Bugs Everywhere is small will be much less painful than making it
+later.
+
+Any objections? Any alternative suggestions?
+
