first stab at the multi channel thing

- renamed create-xml-content-type wizard to create-form wizard and moved it into the wcm source tree
- modified the create form wizard to accept 0 to n template output methods
- changed terminology from presentation template to template output method
- using associations to track output methods
- added file extension as property of templateoutputmethod to parameterize what the name of the output file should be
- auto adding .xml to file name in create web content if none specified.
- making associating an output method with a template optional
