Subject:   - Adds a tag plugin that allows more easily tagging pages.     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.
