Fixed Python-Markdown#73. Codehilite now works in footnotes.

The footnotes treeprocessor must be the first one run so that all others,
including codehilite's, can run on the contents of the footnote div which is
created and inserted by the footnotes treeprocessor.

Thanks to startling for the report.
