Some style fixes. Should fix #1261 and #1675.

Quick fixes to notification code broken in [1831].

Refactoring of the ticket module so that the available ticket fields are collected in a central location. This should result in all modules (ticket, newticket, query, milestone) using the same set of ticket fields. Fixes #1668. Also:
* Add model classes for each of the entities used as ticket fields (component, version, priority, severity, etc)
* [wiki:TracAdmin trac-admin] now uses those model classes instead of direct SQL.
* Improved layout of the form for creating/modifying tickets.
This change is pretty big and may introduce regressions. Please test and provide feedback!

TracDiff: make really obvious that the browser is used to select the target for diff once the base for diff has been selected.

fix wiki export for the generator-based query result (fixes #1650)

Fix time of new attachments. Closes #1646. Thanks to PBruin for the patch.

Adapted expected exception type to [1785].

Fix unit test that was broken in [1816].
