Links like `source:#1` and `log:#1:3` should be equivalent to `source:/#1` and `log:/#1:3`

Show resolution for ticket closure event in timeline.

Set correct mime-types for gifs and pngs.

Added an option for not highlighting CamelCase links when the targeted pages are missing.

However, the link is still shown as missing if the CamelCase link
is enclosed in a description (e.g. `[wiki:DocumentThis To be documented]`
or even `[wiki:DocumentThis]`).

The behavior is made consistent for all the wiki rendering.

For enabling this feature, add the following to the [wiki:TracIni trac.ini]:
{{{
[wiki]
ignore_missing_pages = true
}}}

Should close #476.

''This changeset is dedicated to Pierre Brengard''

Wiki syntax enhancements:

* Make the scheme part of TracLinks conform to RFC 2396 (closes #1968)
* WikiPageNames must begin on a word boundary (closes #1974)
* TracLinks content can be quoted with `"..."` or `'...'` also when
a label is provided (closes #1967)
* Small refactoring of the pre/post rules, making the regexps easier
to understand and eventually customize.

Adapt to changes to static resource handling in [2132].

'''Attention plugin devs''': This changes the `ITemplateProvider` interface and the way you link to static resources.

It also completely removes the `htdocs_location` option. If you want to have the web server serve the static resources, you'll have to do the required configuration in the server configuration (documentation upcoming).

This change fixes #1908.

Somewhat ugly hack to fix #1977. Also, don't show ''milestone'' as available for grouping in the milestone stats.

re-enable fcgi support with a new module compatible with the new Trac license

The license change caused a `trac-admin` test to fail(!). This should fix it.
