Support for InterWiki links

This is a proposal for implementing #40 and #1414 I think it's now ready for testing (see r1912)

Definition

An InterWiki link can be used for referring to a Wiki page located in another Wiki system, and by extension, to any object located in any other Web application, provided a simple URL mapping can be done.

Link Syntax

<target_wiki>(:<identifier>)+

The link is composed by the targeted Wiki (or system) name, followed by a column (e.g. MeatBall:), followed by a page specification in the target.

The target Wiki URL is looked up in a the InterMapTxt wiki page, modelled after ​MeatBall:InterMapTxt.

An addition to traditional InterWiki links, where the target is simply appended to the URL, Trac supports parametric InterWiki URLs: identifiers $1, $2, … in the URL will be replaced by corresponding arguments from a list made up from the page specification split by the ':' token.

Examples

If the following is an excerpt of the InterMapTxt page:

= InterWiki Map =

This is the InterMapTxt wiki page,
modelled after the MeatBall:InterMapTxt page.

Then,

• MoinMoin:InterWikiMap should be rendered as ​MoinMoin:InterWikiMap and the title for that link would be "InterWikiMap in MoinMoin"
• Trac:wiki:InterWiki should be rendered as Trac:wiki:InterWiki, and the title for that link would be "InterWiki in The Official Trac for Trac"
• TracML:004346 should be rendered as ​TracML:004346 and the title for that link would be "004346 in Trac Mailing List Archive" (idea: I should allow positional parameters in the comment as well)
