* Pass a "destpage" parameter to preprocessor and pagetemplate hooks.
This will be the page that a source page will be part of, which is
different than the source page for inlined pages.
* Audited all plugins to endure they pass page, destpage to htmllink
appropriatly. This means inlining of various plugins will not work
properly, with correct links generated.
The meta plugin can also still be used for that, but the tag plugin
also lists a page's tags at the bottom of the page.
- Allows preprocessor directives to have parameters with no specified
value.
- Fixes preprocessor directive parameter parsing so that
foo=bar baz now means "foo=bar" and a "baz" with no value.
* Run pagetemplate hooks when inlining pages so that inlines pages also
list their tags.
* Make all plugins with pagetemplate hooks check that variables exist
on the template before setting them.
* Allow pagetemplate plugins to override *anything* in the template.
* Add a meta plugin, which allows specifying various metadata about pages,
like license and author. It also allows for inserting html link and meta
tags into html, overriding the title, and adding hidden WikiLinks, which
can be useful when using link-based globbing for page categorisation.
* Remove preprocessor directives from inlined pages.
* Allow simple preprocessor directive values to be specified w/o quotes.
