Follow-up to r4747, forgot to replace one usage of wiki_to_link Context method. Fixes #5000.

0.10.4dev: ported r5114 to stable (''bump database_version to 20, so that new and old repository sync scheme won't mix'')

The new repository caching scheme is exclusive to the old one. If by mistake an old code gets to be used and therefore an old style sync, the `youngest_rev` metadata will become inaccurate and the processes will be stuck showing the repository at that `youngest_rev` revision, believing that a sync is in progress...

In order to make sure this can't happen, a version bump is needed.
We take this opportunity to move the transition code (the call to `youngest_rev_in_cache`) into the upgrade file.

Fixed typo from r5112, spotted by Markus Fuchs, thanks!

Follow-up to r4961, avoid to re-raise the TracError we just raised...

Blame: some changes discussed in #4985:
- add an explicit pool to the blame2 call, for consistency with the rest of the SVN bindings usage
- fix ''Annotate'' href so that it looks nicer

reports should not refer to milestones as "Release" since this is not true for all users (fixes #4963)

WorkFlow: slight clarification of the code

WorkFlow: Remove the experiment branch; it's served its purpose.

WorkFlow: Use an OrderedExtensionsOption for configuring the active ticket
action controllers.
