Tiny improvement in tests. This mimetype should likely not vary across platforms and versions.

Closes #3858

MultipleRepositorySupport: bug fixes
- fix browser: TracLinks and remove another spurious `reponame` usage.
- fix diff: links, another typo
- fix AJAX queries in annotate view
- fix sort order direction in path links heading

TracMercurial for MultipleRepositorySupport: ported r6467 from the 0.11 branch of the plugin and fixed plugin version.

TracMercurial for 0.11: fix a typo in a code path reached with recent Mercurial versions. Thanks to Matthew Bloch for reporting the issue.

Fix usage of wrong variable in revision log template (backport of r6458).

MultipleRepositorySupport: add a direct link to the changeset, from the '''Last Change''' column

Should fix #5710.

MultipleRepositorySupport: merge the repository index in the browser template.

This enables us to show at the same time the list of repositories and the top-level entries of the default repository (if any). All those "paths" are visible at the root, so it makes sense to display them all together.

Not to mention that the '''(default)''' repository link in the previous approach can't really be made to work.

Another benefit from this approach is that it's possible to browse in-place across all repositories (and in this case, browsing the default repository works... magic!).

MultipleRepositorySupport: add an index for all the available repositories.

This is the first approach to the feature, using a specific template.

TracMercurial: add support for rendering patches in Mercurial Queue repositories using the patch renderer.

This can be done by setting the `mq` option at repository creation time (e.g. by writing `<reponame>.mq =` in TracIni, when using the default repository provider).

This requires r6459 and its API change for `IRepositoryConnector.get_repository()`.

TracMercurial for MultipleRepositorySupport: use the `reponame` information from the resource in the current context in order to identify the repository for a changeset link.

Also use the `repos.reponame` information, available since r6457.
