Tired of all those uninformative `Workflow: ...` commit log message?
Here's a fix to get even more out of your shortened lines!

This is a follow-up to [1561], which not only simplifies the `shorten_line`
code, but is also more effective at packing multiple lines into one.

Follow-up to the TracDiff branch integration: completed the dummy svn module/objects needed for loading the svn_fs module when the Subversion bindings are not available. Reported by eblot.

WorkFlow:

* Removed redundant workd ''ticket'' from extension methods where it made sense.
* Added `ITicketManipulator.filter_actions()`.
* `ITicketWorkflow.get_action_controls()` now returns a tuple in the form `(label, controls)`.
* `ITicketManipulator` filters now filter the list elements in-place.
* Fixed bug where control tooltips were bleeding into the next control displayed.

WorkFlow:

* Added `ITicketFieldProvider` interface for providing custom ticket fields programmatically.

WorkFlow:

* Default ticket validator now does more actual permission validation.
* `validate_ticket()` is now called ''before'' the ticket is updated. This lets manipulators validate req.args prior to the ticket being updated.
* Added `.title`, adding tooltips to fields.

WorkFlow:

* Broke ticket workflow out into `ITicketWorkflow` and `ITicketManipulator`.
* `ITicketWorkflow` is purely for defining state transitions based on actions.
* `ITicketManipulator` is used for filtering ticket fields before the user sees them, and ticket validation.

WorkFlow:

* Factored out ticket field HDF generation into `fields_to_hdf()` from `NewTicketModule` and `TicketModule`.
* Using `config.getbool()` when extracting custom ticket attributes.
* Field labels and values now use WikiFormatting by default.
* Added a `plaintext` option to disable WikiFormatting for a field.

WorkFlow:

* Ensure ''leave as ...''' action is always present and first.
