Bazaar Explorer 1.0.0beta

Compatibility breaks:

* User-defined hats are now stored in explorer/hats/xxx instead
  of explorer/xxx-hat. Please rename these directories if you
  have personal hats.

New features:

* Kind-specific toolbars are now available and are enabled by
  default. If you are using the ``extended`` toolbar, you may wish
  to change the toolbar contents preference to ``kind-specific``.

* Toolbars can now be customised. See
  http://doc.bazaar.canonical.com/explorer/en/tutorials/customization.html
  for details.

* Preferences are provided to control whether the toolbox is available
  on the various views or not. By default, it is available on the
  status view but not the welcome or repository views. When enabled,
  the Toolbox is now displayed as a tree above the Working Tree browser.
  Clicking on a folder name expands or collapses it. Clicking on an
  tool runs it.

* Text filtering is now supported on the Working Tree browser again.
  If a directory is matched, all the items within it are implicitly
  matched. On large trees, the first time a filter is used, the UI
  may pause momentarily. After that, performance should be reasonable.

* The Browse/Manage/Edit buttons on the Working Tree Browser have been
  replaced with a toolbar of useful actions. Additional actions now
  available are Open, New File, New Directory, Collapse All and
  Expand All. A preference is now available for controlling whether
  double-click open or edits a file as well.

* Bazaar Explorer now provides a cool new extensions architecture
  called "Accessories". Many accessories are provided out-of-the-box
  (including ~20 hats for various Launchpad projects) and plugins
  may add their own by simply adding various files to their 'explorer'
  directory.

  Accessories and the objects they provide can be browsed and
  managed using the new Accessories dialog under the File menu.

* Hat switching is now implicit based on configured rules. When
  opening a location which looks like one matching an installed hat,
  the user is given the option of associating that location with the
  suggested hat. Rules can also be added or deleted by editing your
  explorer.conf file directly. (The Accessories dialog will gain
  that feature soon hopefully.)

* A File > Open Recent menu is now provided. This displays the last 20
  opened locations. The welcome page now has a 'Recently Opened' panel
  for selecting a location from history as well.

* A custom switch dialog is now provided that makes switching between
  branches in a colocated workspace easier. (Neil Martinsen-Burrell)

* Plugins can now override Bazaar Explorer's custom dialogs in order
  to provide additional or alternative functionality.

Improvements:

* The *Advanced Commands* action has been renamed to *All Commands* to
  reflect the fact that this dialog exposes every command (including
  those from plugins), not just advanced core bzr commands. The icon
  has been changed to Bazaar's logo as well, rather than a terminal.

* Tool folders may now have an icon and contain predefined actions.
  Existing contents in a folder can also be replaced instead of
  appended to by specifying 'existing="replace"' as a parameter
  in the ToolFolder object inside an xml file containing tools
  (or toolbars).

* Custom logos can be provided for use on tool actions and folders.

Translations:

* Added translations for Hebrew and Hungarian.
* Updated translation for English (UK).
