cldr/supplemental Intern tests: Add getFirstDayOfWeek, use strictEqual
Add test for dojo/cldr/monetary
Convert rpc tests from doh to intern
rpc Intern tests: Replace JSONP test with one using a local service

The Yahoo service used by the existing DOH test appears to be dead.

Unfortunately, this currently doesn't work, because JsonpService uses
dojo/io/script which fails to account for non-variable-friendly characters
such as the hyphen in `dojo-testing`, so we either need to tweak
dojo/io/script or rename `dojo-testing`.
