[Wtr-general] Js popup unit tests

[Carlos.Fernandez at usitc.gov]

-->  I chaulked this up to the fact that a 1.5.x dev gem has been released
for over a year.

I just discovered the watir forum -- google sure is helpful ;) -- and realized the watir v1.4 does not support IE 7.  However, I also had "hang-ups" when I ran the watir v1.5 jscript_test.rb.
