add underlay files for listdirectives

As was noted, 'listdirectives' didn't include the underlay files that make
it really worthwhile.  I've just gone through all the plugin
documentation, modified it to remove installation information and renamed
the files to match the directives rather than the plugins.  This can now
serve as useful underlay.

I've only gone through plugins in the 'plugins' dir.  I did not go through
the 'contrib' dir.

+The `calendar` directive is supplied by the [[!iki plugins/calendar]] plugin.
+
+This directive displays a calendar, similar to the typical calendars shown on
+some blogs.
+
+# examples
+
+	\[[!calendar ]]
+
+	\[[!calendar type="month" pages="blog/* and !*/Discussion"]]
+
+	\[[!calendar type="year" year="2005" pages="blog/* and !*/Discussion"]]
+
+This plugin is inspired by the calendar plugin for Blosxom, but
+derives no code from it. This plugin is essentially a fancy front end
+to archives of previous pages, usually used for blogs. It can produce
+a calendar for a given month, or a list of months for a given year.
+
+This plugin requires extra setup.  See the plugin documentation for details.
+
+## usage
+
+* `type` - Used to specify the type of calendar wanted. Can be one of
+  "month" or "year". The default is a month view calendar.
+* `pages` - Specifies the [[ikiwiki/PageSpec]] of pages to link to from the
+  month calendar. Defaults to "*".
+* `archivebase` - Configures the base of the archives hierarchy. The
+  default is "archives". Note that this default can also be overridden
+  for the whole wiki by setting `archivebase` in ikiwiki's setup file.
+* `year` - The year for which the calendar is requested. Defaults to the
+  current year.
+* `month` - The numeric month for which the calendar is requested, in the
+  range 1..12. Used only for the month view calendar, and defaults to the
+  current month.
+* `week_start_day` - A number, in the range 0..6, which represents the day
+  of the week that the month calendar starts with. 0 is Sunday, 1 is Monday,
+  and so on. Defaults to 0, which is Sunday.
+* `months_per_row` - In the annual calendar, number of months to place in
+  each row. Defaults to 3.
+
+## CSS
+
+The output is liberally sprinkled with classes, for fine grained CSS
+customization.
+
+* `month-calendar` - The month calendar as a whole.
+* `month-calendar-head` - The head of the month calendar (ie,"March").
+* `month-calendar-day-head` - A column head in the month calendar (ie, a
+  day-of-week abbreviation).
+* `month-calendar-day-noday`, `month-calendar-day-link`, 
+  `month-calendar-day-nolink`, `month-calendar-day-future`,
+  `month-calendar-day-this-day` - The day squares on the month calendar,
+  for days that are not in the month (before or after the month itself), that
+  don't have links, that do have links, that are in the future, or are that
+  are the current day, respectively.
+* `Sunday`, `Monday`, `Tuesday`, ... - Each day square is also given a class
+  matching its  (localised) day of week, this can be used to highlight
+  weekends.
+* `year-calendar` - The year calendar as a whole.
+* `year-calendar-head` - The head of the year calendar (ie, "2007").
+* `year-calendar-subhead` - For example, "Months".
+* `year-calendar-month-link`, `year-calendar-month-nolink`,
+  `year-calendar-month-future`, `year-calendar-this-month` - The month
+  squares on the year calendar, for months with stories,
+  without, in the future, and currently selected, respectively.
