Added smart_strong extension. Fixes Issue #17. Like PHP Markdown Extra, we now include smart handling of double underscores (not just single underscores). The new behavior may be called seperately as the 'smart_strong' extension or as part of the 'extra' extension.

+Smart_Strong
+------------
+
+Summary
+
+The Markdown Smart_Strong Extension adds smarter handling of double underscores
+within words. This does for double underscores what 'smart_emphasis' does for 
+single underscores.
+
+The Smart_Strong Extension is included in the standard Markdown library.
+
+Usage
+-----
+
+    >>> import markdown
+    >>> markdown.markdown('Text with double__underscore__words.', \
+                          extensions=['smart_strong'])
+    u'<p>Text with double__underscore__words.</p>'
+    >>> markdown.markdown('__Strong__ still works.', \
+                          extensions=['smart_strong'])
+    u'<p><strong>Strong</strong> still works.</p>'
+    >>> markdown.markdown('__this__works__too__.', \
+                          extensions=['smart_strong'])
+    u'<p><strong>this__works__too</strong>.</p>'
+
+This extension is also included with the [[Extra]] Extension. You may call that
+extension to get this behavior with all the other features of 'Extra'.
+
+    >>> markdown.markdown(text, extensions=['extra'])
