TracTimeline: restore the previous style of presentation for the TicketTypes

Always trigger a `CachedRepository.sync` at the very start of a request, then try to stay within that "snapshot" view of the repository. Fixes #4132.

cosmetic fix for reusing the run_once value.

Manually backported [3978/trunk/trac/web/main.py], so that the thread-specific cleanup is done in any case but CGI.

0.10-stable: Backported r4252, as this makes cache.py maintenance easier (''fix #4137'')

Should fix up #3780 and #4188 (issues with email notification with `always_notify_updater` option)

Ported r4296 to 0.10-stable (fixes #1440)

small cleanup to r4296

require `TICKET_ADMIN` to assign tickets to a closed milestone (fixes #1440)

import `setuptools` specifically for the "develop" command, all other commands still use `distutils` (fixes #3743)
