Added an asciidoc writer (partial).

Still TODO:

- documentation in README
- add default.asciidoc to templates/
- lists
- tables
- proper escaping
- footnotes with blank lines - print separately at end?
  currently they are just ignored.
- fix header (date gives weird result on pandoc README)

+Footnotes
+---------
+
+Here is a footnote reference,[^1] and another.[^2] This should *not* be a

+
+> Notes can go in quotes.[^4]
+
+1.  And in list items.[^5]
+
+This paragraph should not be part of the note, as it is not indented.
+
+[^1]: Here is the footnote. It can go anywhere after the footnote reference.
+    It need not be placed at the end of the document.
+
+[^2]: Here’s the long note. This one contains multiple blocks.
+
+    Subsequent blocks are indented to show that they belong to the footnote
+    (as with list items).
+
+          { <code> }
+
+    If you want, you can indent every line, but you can also be lazy and just
+    indent the first line of each block.
+
+[^3]: This is *easier* to type. Inline notes may contain
+    [links](http://google.com) and `]` verbatim characters, as well as
+    [bracketed text].
+
+[^4]: In quote.
+
+[^5]: In list.
