Subject: Add support for partials and path segments for Handlebars.

This introduces support for some missing features to the Handlebars lexer:
Partials and path segments. Partials mostly appeared to work before, but the
`>` in `{{> ... }}` would appear as a syntax error, as could other
components of the partial. This change introduces support for:

* Standard partials: `{{> partialName}}`
* Partials with parameters: `{{> partialName varname="value"}}`
* Ddynamic partials: `{{> (partialFunc)}}`
* Ddynamic partials with lookups: `{{> (lookup ../path "partialName")}}`
* Partial blocks: `{{> @partial-block}}`
* Inline partials: `{{#*inline}}..{{/inline}}`

It also introduces support for path segments, which can reference content in
the current context or in a parent context. For instance, `this.name`,
`this/name`, `./name`, `../name`, `this/name`, etc. These are all now tracked
as variables.

+    The Pygments Markdown Preprocessor
+    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+    This fragment is a Markdown_ preprocessor that renders source code
+    to HTML via Pygments.  To use it, invoke Markdown like so::
+
+        import markdown
+
+        html = markdown.markdown(someText, extensions=[CodeBlockExtension()])
+
+    This uses CSS classes by default, so use
+    ``pygmentize -S <some style> -f html > pygments.css``
+    to create a stylesheet to be added to the website.
+
+    You can then highlight source code in your markdown markup::
+
+        [sourcecode:lexer]
+        some code
+        [/sourcecode]
+
+    .. _Markdown: https://pypi.python.org/pypi/Markdown
