Add support for displaying list of changesets and ranges of changesets in TracRevisionLog by extending the TracLinks `log:` syntax.

Now, in addition to a single range `[12:23]` which was already supported, one can list multiple ranges like `[12:34,45:50]` (or equivalently `[12-34,45-50]`). Single changeset numbers can also be listed instead of ranges, e.g. `[1,2,3-6,10,11]`.

Further simplification of the TracBrowser's IWikiSyntaxProvider

SpamFilter plugin: Another follow-up to [4079], more fixes in the ClearSilver template.

Follow-up to [4079]: show the full content in the spam log entry detail panel also when using ClearSilver templates.

SpamFilter plugin: add log entry detail view to monitoring admin panel.

Refactoring of the TracLinks `source:` and `log:` resolver syntaxes:
- there's no point to reuse the share the same function between `source:` and `log:` resolver: they already diverge and they're going to diverge more (support of revision ranges in the `log:` resolver)
- fixes remaining `log:` resolver syntax unit-test failures

Fix browser wikisyntax test according to:
- "#" can no longer be used to specify the revision (r4075)
- no "%20" to escape whitespace; use regular TracLinks quote mechanism (`source:"path

Follow-up to r4067: `extra` needs to be reset

Added support in `source:` TracLinks for specifying ranges of lines to be highlighted. Original patch by Tim Hatch. Closes #2764.

Follow-up to r4030: the args may already contain `asc` or `sort`, we have to filter them out in this case.
