updated Nick's dojo/parser tests

dojo/parser tests were updated to support the new mappings and fix a couple issues
* update parser.html to use dojo-testing and correctly reference classes
* moved the global delcare statements into the setup function so it targeted the testing frame document
* limited tests to only run in a browser

I was not able to update the test to use dojo-testing/parser.  Most of the tests fail when I do and it seems as if parsing just does not happen.
