move contrib plugin directives out of ikiwiki/directive

Problem is that ikiwiki/directive is turned into an underlay and added to
all wikis. And the test suite checks it for broken links and turns some up.
So it's not appropriate for contrib plugin's directives to be documented
in there.

+The `ftemplate` directive is supplied by the [[!iki plugins/contrib/ftemplate desc=ftemplate]] plugin.
+
+This is like the [[ikiwiki/directive/template]] directive, with the addition
+that one does not have to provide all the values in the call to the template,
+because ftemplate can query structured data ("fields") using the
+[[plugins/contrib/field]] plugin.
+
+Templates are files that can be filled out and inserted into pages in
+the wiki, by using the ftemplate directive. The directive has an id
+parameter that identifies the template to use.
+
+Additional parameters can be used to fill out the template, in
+addition to the "field" values.  Passed-in values override the
+"field" values.
+
+There are two places where template files can live.  One is in the /templates
+directory on the wiki.  These templates are wiki pages, and can be edited from
+the web like other wiki pages.
+
+The second place where template files can live is in the global
+templates directory (the same place where the page.tmpl template lives).
+This is a useful place to put template files if you want to prevent
+them being edited from the web, and you don't want to have to make
+them work as wiki pages.
+
+### EXAMPLES
+
+#### Example 1
+
+PageA:
+
+    \[[!meta title="I Am Page A"]]
+    \[[!meta description="A is for Apple."]]
+    \[[!meta author="Fred Nurk"]]
+    \[[!ftemplate id="mytemplate"]]
+
+Template "mytemplate":
+
+    # <TMPL_VAR NAME="TITLE">
+    by <TMPL_VAR NAME="AUTHOR">
+
+    **Summary:** <TMPL_VAR NAME="DESCRIPTION">
+
+This will give:
+
+    <h1>I Am Page A</h1>
+    <p>by Fred Nurk</p>
+    <p><strong>Summary:</strong> A is for Apple.
+
+#### Example 2: Overriding values
+
+PageB:
+
+    \[[!meta title="I Am Page B"]]
+    \[[!meta description="B is for Banana."]]
+    \[[!meta author="Fred Nurk"]]
+    \[[!ftemplate id="mytemplate" title="Bananananananas"]]
+
+This will give:
+
+    <h1>Bananananananas</h1>
+    <p>by Fred Nurk</p>
+    <p><strong>Summary:</strong> B is for Banana.
+
+#### Example 3: Loops
+
+(this example uses the [[plugins/contrib/ymlfront]] plugin)
+
+Page C:
+
+    ---
+    BookAuthor: Georgette Heyer
+    BookTitle: Black Sheep
+    BookGenre:
+      - Historical
+      - Romance
+    ---
+    \[[ftemplate id="footemplate"]]
+
+    I like this book.
+
+Template "footemplate":
+
+    # <TMPL_VAR BOOKTITLE>
+    by <TMPL_VAR BOOKAUTHOR>
+
+    <TMPL_IF BOOKGENRE>(
+    <TMPL_LOOP GENRE_LOOP><TMPL_VAR BOOKGENRE>
+    <TMPL_UNLESS __last__>, </TMPL_UNLESS>
+    </TMPL_LOOP>
+    )</TMPL_IF>
+
+This will give:
+
+    <h1>Black Sheep</h1>
+    <p>by Georgette Heyer</p>
+
+    <p>(Historical, Romance)</p>
+
+    <p>I like this book.</p>
+
+### LIMITATIONS
+
+One cannot query the values of fields on pages other than the current
+page.  If you want to do that, check out the [[plugins/contrib/report]]
+plugin.
