Remove German message strings.

Follow-up to r5814: ticket property diffs are now also rendered specially in ticket preview mode.

Respect new lines from the original text in ticket descriptions and comments. Implements #2914.

FieldRefactoring: most of the changes in the branch were integrated in [5812:5813], with minor adaptations. Further changes will happen on a re-created branch at some point in the future, targeting [milestone:0.12].

Make `format_author` helper method part of the public API of the Chrome component. This will help plugin to be consistent with the permission to view e-mail addresses (see #153)

Set svn:eol-style property to native on a bunch of .py files

Make db upgrade step 20 more robust.

Follow-up to r5812: diff properties are now also rendered specially in the ticket diff view and in the ticket RSS log.

The functionality of #5126 is now complete.

Improved rendering of ticket properties (merged from the FieldRefactoring branch).

The rendering of properties is now done in `_prepare_fields` in the controller rather than in the template. That method can therefore be called by `_insert_ticket_data` (for the normal ticket display) and when previewing a new ticket before submission. In the future, that method will delegate the rendering to dedicated field renderer classes and/or property renderer components.

The `_prepare_fields` method implements a few additional rendering enhancements:
- E-mails in the CC: list are obfuscated if needed (implements #5126)
- link to milestones (implements #449)
- "yes/no" for checkbox custom fields instead of the "1/0" values

Improved rendering of ticket property changes (merged from the FieldRefactoring branch).

The rendering of property change is now done in `rendered_changelog_entries` in the controller rather than in the template. That method can therefore be called by `_insert_ticket_data` (for the normal ticket display) and by `_get_history` (displaying ticket version changes). In the future, that method will delegate the rendering to dedicated field renderer classes and/or property renderer components.

The `rendered_changelog_entries` method implements a few additional rendering enhancements:
- improved visualization of changes to the Ticket CC list (added/removed and obfuscation of e-mail addresses if needed) (fixes #5126)
- similar added/removed rendering for changes to the keyword list
- set/unset for checkbox custom fields
