fix some domita_test failures on opera 10

This fixes some test failures on Opera 10

http://code.google.com/p/google-caja/issues/detail?id=1141
  several tests failed, because color comparisons failed,
  because when reading a colorname like 'red', Opera gives
  you the string '"red"'.

http://code.google.com/p/google-caja/issues/detail?id=1166
  testRowCell failed because it's testing for a specific
  exception message with assertEquals, but Opera appends
  some extra info to the end of thte message.

  I'm not sure why the commonJsModule tests were failing,
  but they're not failing now.

with this change, there's only 1 failure remaining on Opera:
http://code.google.com/p/google-caja/issues/detail?id=1165
  testCustomEvents still fails.  I made some changes to
  report the problem better.

oh, wait.  the commonJsModule tests are missing, not fail.
and they're still missing.  so that's still unresolved.

File tests/com/google/caja/plugin/domita_test_untrusted.html (right):

http://codereview.appspot.com/157123/diff/1/4#newcode537
tests/com/google/caja/plugin/domita_test_untrusted.html:537: if (cssColorString
=== '"' + expected.name+ '"') { return; }
OK.
Need space before +

http://codereview.appspot.com/157123/diff/1/4#newcode2265
tests/com/google/caja/plugin/domita_test_untrusted.html:2265:
assertComputedStyle(block, null, 'cursor', 'crosshair');
Ok, so you're testing that the style was applied, and so the cursor:crosshair
added in the previous file is a canary.

tests/com/google/caja/plugin/domita_test_untrusted.html:2949: assertColor({
name: 'blue', rgb: 0x0000ff }, el.style.borderTopColor);
cool

tests/com/google/caja/plugin/domita_test_untrusted.html:3090: assertTrue(new
RegExp('Index size error').test(e.message));
cool
