Blame branch: add <meta name="ROBOTS"> header for the browser view, as appropriate.

Follow-up to r4536, fix unit tests. Also took this opportunity to clean up that file which apparently contained 3 times the same content...

Timeline link resolver branch (#975):

This implements a `timeline:` link resolver prefix.
The argument must be a date string in the ISO:8601 format, with at least the year and the month specified.

Besides TracLinks, there are many more ways to go back to the timeline, now: I modified the format_datetime helper function and the dateinfo macros so that we get links to the timeline from various places (e.g. changeset time, ticket created and last modified time, browser age, wiki history, ...).

Also, there are some fine tuning to the datetime utilities in `trac.util.datefmt`:
- the `format_*` functions supports an `'iso8601'` format
- `parse_date` can also understand this format
- fixed offsets timezones are now using strings like "GMT +01:00" instead of the more confusing 'Etc/GMT-1' one (see discussion in #975).

Creating a work branch to finalize #975.

Minor improvement to the `DefaultTicketGroupStatsProvider`: only call refresh_calcs once.

In roadmap and milestone view, also provide a summary of the total count of tickets, and a link to all tickets for the milestone. Implements #3233.

0.10.4dev: ported r4532-4533 to 0.10-stable (''trac-post-commit-hook, #1310 and #1602'')

Follow-up to r4532, remove my own settings

trac-post-commit-hook enhancements from markus. Fixes #1310 and #1602.

TracMercurial for 0.11: follow-up to r4530. The plugin is now compatible with the upcoming IPropertyRenderer interface. It will also stay compatible with the old `Changeset.get_properties` API until 0.11 gets released.
