TracMercurial for 0.11: a few optimizations for the revision display methods.

It seems that avoiding `repo.lookup` in most cases makes the whole thing feel much more responsive.

Oops, forgot to rename this `render_macro` to `expand_macro` during the [4621] API change. Fixes #4602.

Annotation API doc change: it's not advised anymore to use short revs (as they're probably not always unique identifiers in all backends). Instead, we call `Repository.short_rev` where appropriate (see also #3533).

Fix ''System Information'' in error.html. Follow-up to r4577: don't introduce newlines within a wiki table cell.

Fix the !PlainTextRenderer so that it also works when no annotations are requested. The problem was apparent in code blocks when the highlighter(s) failed to render the block and the plain text renderer was used as a fallback.

Thanks to zimbatm on IRC for helping me to track down the issue.

Follow-up to r4399 and r4597.

Follow-up to r4636, some fine tuning ...

Improve the prepared description text for semi-automatic ticket creation

Clarify `Changeset.get_changes` API documentation. Fixes #4595.

Fix patch renderer unit test broken in [4622].

Simplify `trac.loader` a bit by:
* making use of the fact that SetupTools is now a mandatory dependency, and
* dropping support for plugins not using the `trac.plugins` entry point.
Also, load `.py` source (single-file) plugins after Python eggs (closes #4383).
