that given link points based on the page doing the linking. Note that this
could make such PageSpecs match different things than before, if you
relied on the old behavior of them only matching the raw link text.
* This required changing the match_* interface, adding a third parameter.
* Allow link() PageSpecs to match relative, as is allowed with globs.a
* Add postform option to inline plugin.
* Add an bug tracker to the softwaresite example.
* Add a "conditional" plugin, which allows displaying text if a condition
is true. It is enabled by default so conditional can be used in the
basewiki.
* Use conditionals in the template for plugins, so that plugin pages
say if they're currently enabled or not, and in various other places
in the wiki.
