Some wiki formatter cleanup, in follow-up to r3376 and r3377:
* removed the special handling done for MoinMoin `["internal free link"]`
syntax introduced in r3295, as this now also works thanks to r3376
* fix the relative link syntax broken by r3376, i.e. things like:
* `[/download Download area]` ''link relative to the server's root URI
* `[../other see other]` ''link relative to the current location''
* fix some macro calls counter examples
* added a regression test for #3245

setuptools branch: starting the required changes.

Init sandbox branch for setuptools adoption as proposed in trac-dev:590.

Remove unused `doctrim` function.

WorkFlow: Merged log:trunk@...:3377 (painful!)

Fix for bug in wiki title linked shortcuts.

Removed spurious debug statement, `setup.py` now creates stub `conf` and
`plugins` global directories, and added Wiki short-cut aliasing
(eg. `[WikiPage some title]`) closing #3240.

Display milestone due date in roadmap, making it consistent with current milestone view. Closes #2226.

Fix for [[html(¶)]] appearing at the start of comment headings.

Minor layout change to ticket replies, floating links to the right.
