Merge assorted bugfixes and optimizations.

Highlights:
  * `be new` adds creator field like its supposed to (oops :p).
  * `be list --xml` uses <be-xml> format (was <bugs>).
  * `be import-xml` handles root comments appropriately.
  * `be` raises an appropriate help message.
  * `be help` works.
  * `be html` prints Comment.id.user() information.
  * better SavedSettingsObject._get_saved_settings() avoids data loss.
  * be-mbox-to-xml -> be-mail-to-xml and adds assorted format support.
  * be-xml-to-mbox and be-handle-mail work with new libbe layout.
  * BugDir.uuids() now caches on-disk uuids for speed.
  * Mercurial detection works for mercurial <= 1.1.2 _and_ >= 1.2
  * Fix bugs in VCS._children() relative/absolute path handling.

+
+Ok, I've got CFBE working with my BE head:
+  http://www.physics.drexel.edu/~wking/code/hg/cfbe/
+However, I haven't reworked CFBE to take advantage of the new command
+structure.
+
+We'll need to extend libbe.command.base.Argument a bit as we work this
+out, but I expect we can auto-generate handlers for various commands
+with something along the lines of:
+
+<snip web.py>
+
+class CommandHandler (object):
+    def __init__(self, command):
+        self.command = command
+    def __call__(self, *args, **kwargs):
+        if GET:
+            template = self.env.get_template('command.html')
+            return template.render(command=self.command)
+	else:
+            try:
+                ret = libbe.ui.command_line.dispatch(
+                    self.command.ui, self.command, *args, **kwargs)
+            except libbe.command.UserError, e:
+                HANDLE ERROR
+            stdout = self.command.ui.get_stdout()
+            DISPLAY STDOUT OR REDIRECT...
+
+class WebInterface (libbe.command.UserInterface):
+    ...
+    def add_commands(self):
+        for command_name in libbe.command.commands():
+            Class = libbe.command.get_command_class(
+                command_name=command_name)
+            command = Class(ui=self)
+            self.command_name = cherrypy.expose(
+                CommandHandler(command))
+
+</snip web.py>
+
+<snip command.html>
+
+<form id="command-form" action="/command" method="post">
+    <fieldset>
+        {% for option in command.options %}
+	  {{ option_form_html(option) }}
+        {% endfor %}
+        {% for argument in command.args %}
+	  {{ argument_form_html(argument) }}
+        {% endfor %}
+    </fieldset>
+</form>
+
+{{ command.help() }}
+
+</snip command.html>
+
+Of course, incorperating interactive functionality in command output
+(i.e. changing the bug target from the bug-show page), doesn't fit
+into this model.  To do that, we'd have to abstract the default
+command output the way we've already abstracted the commands and their
+input...  This sounds like a lot of work, and it is, but the goal is
+that BE adds functionality (new commands, option, etc.), and CFBE,
+be-handle-mail, etc. automatically incorperate the new stuff.
+
+Thoughts?
