add support for jasmine-node tests
a better filter to pick out the jasmine-node vs jasmine files
support for running all jasmine-node tests recursively.  todo: add support to filter out non-node .js files i.e. supporting files in a subfolder, etc.
add text to jasmine html results file to indicate that jasmine-node was used (jasmine-node ships with jasmine 1.3.1)
fixed a bug where when the jasmine-node test in the working set is selected and when run, the test would fail do to null pointer reference - checked for undefined vs null to fix it.
add a jasmine-node sample
merge test262 functionality changes
