Fix problem with cgi.escape being depricated a different way. This way uses anypy and is cleaner. Also fixes incorrect/incomplete change that resulted in escaped in TAL generated by TALInterpreter.py. The escaped quotes break javascript etc. defined using tal string: values. TODO: add test cases for TAL. This wouldn't have snuck through for a month if we had good coverage of that library.
