![[MacroList]] now copes with buggy macros if they raise an exception during the generation of their description. Closes #2917.

WorkFlow:

* Fixed a bug with select field types being immutable.

WorkFlow:

* Merged r3067
* Added TracIni documentation for `ticket-status` and `ticket-actions` sections.
* Documented fields in preparation for future `TracTicketTypes` macro.
* Converted awesome English spelling (serialise) to perverse American spelling (serialize).

Little cleanup of a method left in r3067 by mistake

Follow-up to r3055: changed `IConfigurable.get_config_options` to `IConfigurable.get_config_sections` and make it generate `ConfigSection` objects.

Now, `IConfigurable` implementers can also document their configuration sections,
with wiki text that should be inserted before (''header'') or after (''footer'')
the configuration options table.

WorkFlow:

* Merged attach-on-create, query navigation and permission enforcement into unified ticket module.
* Fixed bug where a ticket had an empty status upon creation.
* Most permissions are now enforced in the default validator, though the `TicketModule` does some basic viewable/createable enforcement.
* No longer allow create/update when there are validation errors.
* Added titles to the form field control renderers.
* Query now effectively defaults to `status!=closed` by default.

WorkFlow:

* The roadmap now generates a valid query when used with custom ticket states. Closes #2941.

WorkFlow:

* States defined in the `[ticket-status]` TracIni section are now automatically added to the list of available states. This allows queries to work correctly. Fixes #2898.

WorkFlow:

* More validation enhancements. Most fields should be validating now.
* Fixed a bug where query was failing.
* Added `ITicketEnumContributor` which lets plugins programatically provide extra status, priorities, etc.
