Wiki unit-tests restructuration.

* Make it possible to add a title for wiki tests.
* Added such a descriptive title for all the existing tests,
with a comment indicating what should be done with the test
* `(MOVE)` means the test will be moved closer to the
corresponding `IWikiSyntaxProvider` (similar to what was
done in r3122)
* `(FIXME)` means the test should be changed in order to use
a generic link resolver

In TracBrowser, move the logic for building the hrefs used for changing the sort order from the template to the python code. This fixes #3033.

Experimental hooks for pre and post processing of wiki page changes (for spam filtering).

Add hooks for listening to, and potentially rejecting, ticket changes, based on patch by Alec. Closes #2176 and #3029.

Adding a regression test for #2665.

Don't allow the usage of "%20" in WikiPageNames in order to represent a space.

Wiki page names containing spaces can be build using the usual
[TracLinks#QuotingspaceinTracLinks target quoting rules]
in explicit Wiki links.

This was done in order to fix #2665.

Corrected Jonas family name's UTF-8 encoding messed-up in r3141

Unicode consolidation: use `to_unicode(x)` instead of `unicode(x)` when `x` might be a `str` object.

This is especially true when the content may come from a plugin,
e.g. the fix in the `WikiProcessor` will likely fix #3024.

`to_unicode` will always succeed at producing some unicode object,
whereas the basic `unicode(x)` call can raise an `UnicodeDecodeError`
when given an arbitrarily encoded string.
Thus, `unicode(x)` should only be used when we're confident that `x`
is already an `unicode` or derived object, like `Markup`, or is some other type that can be safely converted to `unicode`.

This also fixes the problems that happened in TracAdmin
when `sys.stdin.encoding` was `None` (#3018).

''Last minute, the typo introduced in r3138 in `format_datetime` is fixed,
and mgood actually already fixed #3018 in r3140 :)''

trac-admin: handle unicode conversion when `sys.stdin.encoding` is `None` (fixes #3030)
