Adds an opt-in wiki-links extra that turns [[Page Name]] into a link to another page, modelled on the wikilinks extension from Python-Markdown. The generated URL and CSS class are configurable through the base_url, end_url and html_class options, plus an optional build_url callable for full control over the href. The extra is off by default and the anchor is hashed so later stages leave labels and URLs containing underscores alone. Addresses trentm#221.

wiki-linksextra so that[[Page Name]]turns into a link to another page, which is the feature asked for in #221. It is modelled on the wikilinks extension from Python-Markdown, so the target URL and CSS class are configurable:base_url,end_urlandhtml_classcover the common cases, and there is an optionalbuild_urlcallable if you want full control over the href. For example:Like the other extras it is off by default, so existing output is unchanged. The generated anchor is hashed the same way
link-patternsdoes it, which keeps the later stages from mangling labels or URLs that contain underscores. Inline code and fenced blocks are left alone because they are already hashed by the time the extra runs.I added two tm-cases (a default one and one exercising the options) and a CHANGES entry.
