Fix NameError in run-tests.py
Fix Python 3 compat in Attr_list. Fixes #218.
HeaderID Ext now handles raw html in ids. Fixes #232
Serializers now preserve case of tags.

It is up to the markdown code (and extension authors to make sure tags are
of the correct case (there may be cases were an extension might need to
mix cases - which should be preserved). Fixes #237. Thanks for the report
@eichin.
Allow extensions to register serializers

Setting output_format must happen after extensions are loaded. Only in that
way can an extension register a serializer so that it will then be available
to be used with the output_format keyword. A test has been added to avoid
this regression from happening again in the future.

Fixes #238, partially reverses commit 41cc055 and provides a better fix for
Extended headerid's rawHTML in id handling to toc ext.
Deprecated CodeHilite's force_linenos config setting.

It was previously marked pendingdeprecation in v2.3. Now deprecated.
Added release notes for pending release of v2.4.

Since adding the new smarty extension, the nex release it more than just a
bugfix release.
Allow fenced_code to be configurable in subclasses.

Not sure why I was using global variables here. Anyway. Fixed now.
Thanks to Andrew for pointing it out.

Typo in util.py
Ensure each term on def list maintains its own loose status.

Previously, the code was ignoring whether this was a new term when determining
whether the currect item should be loose or not. Fixes #243. Thanks for the
report @Anomareh.
