Use an external dojo 1.10.0 for writing tests

- Add dojo-1.10.0 dependency to package.json
- Update test config to map "dojo-testing" to the dojo-under-test
- Update all tests to use the right dojo for the right thing
Don't use intern/dojo for writing tests -- use an external dojo.

This commit converts the doh tests into unit tests. It merges the divergences
in the standard and quirks mode tests, and flags those tests which are
specific to quirks mode in case we want to reenable these tests later.
