Bazaar Explorer 0.10.0

Please edit ~/.bazaar/explorer/tools.xml (or the equivalent location
on Windows) and rename the top level folder to "My Tools".

Compatibility breaks:

* The Plugins and Advanced Commands actions have moved from the
  Tools menu into the main Bazaar menu.

New features:

* Bazaar > Advanced Commands now launches the qrun dialog by default.
  A preference is provided for users who prefer the old behaviour of
  launching a terminal instead.

* The status bar now provides a button for running lp-open.
  For a repository, the project page on Launchpad can be opened from
  that button if it can be intelligently guessed.

* For feature branches, a details panel is now displayed showing the
  submit delta so far. (This replaces the "Branch changes" experimental
  feature which is no longer available.)

* Numerous useful links have been added for Bazaar Support and
  Bazaar Development as standard tools.

* A toolbox now shares space with the working tree browser. This
  provides faster access to the standard tools, your personal tools
  and tools provided by the current hat, if any.

* A dialog is now provided for adding Tools.

Improvements:

* The default and extended toolbars now include an Advanced action.

* F8 is now a keyboard shortcut for Advanced Commands.

* The Preferences dialog now uses tabs rather than group boxes.
  (This arguably makes preferences harder to find but it scales
  better as new preferences are added later.)

* Custom dialog boxes are now individually configurable so that
  heavyweight checkouts can be used with the qgetnew dialog, but
  feature branches can be made with the custom init dialog.
  The old 'custom-dialogs' setting is no longer used so you
  can delete it from explorer.conf if you wish.

Bug fixes:

* Allow switch action for bound branches (heavyweight checkouts).
  (A. S. Budden, Bug #479356)

* Create parent(s) of ~/.bazaar/explorer directory if needed.
  (A. S. Budden, Bug #474812)

Translations:

* Added Greek translation.
