Flatpages first pass

This fixes the template loader so that it can load plugin templates.

This adds code for registering template paths so that plugins can add
their own templates.

This adds the base code for the flatpagesfile plugin. It doesn't serve
pages, yet, but it's pretty close.

+ README
+========
+
+This is the flatpages file plugin. It allows you to add pages to your
+MediaGoblin instance which are not generated from user content. For
+example, this is useful for these pages:
+
+* About this site
+* Terms of service
+* Privacy policy
+* How to get an account here
+* ...
+
+
+How to add pages
+================
+
+To add pages, you must edit template files on the file system in your
+`local_templates` directory.
+
+The directory structure looks kind of like this::
+
+    local_templates
+    |- flatpagesfile
+       |- flatpage1.html
+       |- flatpage2.html
+       |- ...
+
+
+The ``.html`` file contains the content of your page. It's just a
+template like all the other templates you have.
+
+Here's an example::
+
+   {% extends "flatpagesfile/base.html" %}
+   {% block mediagoblin_content %}
+   <h1>About this site</h1>
+   <p>
+     This site is a MediaGoblin instance set up to host media for
+     me, my family and my friends.
+   </p>
+   {% endblock %}
+
+
+.. Note::
+
+   If you have a bunch of flatpages that kind of look like one
+   another, take advantage of Jinja2 template extending and create a
+   base template that the others extend.
