Devel template schema.py file references a class patches, but has no patches.X.html file.
It does have patch.X.html. Changed class to patch from patches, but kept property name
patches. Followed through with changes to issue.item.html

Fixed a couple of incorrect comments saying patches is inherited from IssueClass in
devel and responsive schema.py.

In devel template alphabetized property list for a permission.

Added patch property to bug class in responsive template to match devel template. Responsive 
template has patch.X.html files.

This gets the schema for devel and responsive identical since they are supposed to implement
the same schema.

This doesn't fix the initial issues, but the cleanup might make dealing with it easier.
