Comment 2 for bug 101818

I've reviewed the changes, and I see no obvious problems, so I would say check
them in. (Note that for 1.6 the change in kupusilvatools.js has to happen in
Silva/kupu, and not in kupu itself.) If you've done that, please set this issue
to testing, and I will assign it to someone here to test.

TESTING NOTES:

- Run the silva tests, I expect the change may impact the xml export/import
tests. If not, we may want to add tests for checkbox parameters.
- Test Codesources having checkbox parameters with and without xslt rendering,
(once the other issue with that is fixed) to see whether the codesources behave
as expected.
