JavaScript performance comparison

Revision 698 of this test case created

Info

A brief comparison of some JavaScript templating engines on a short template: 6 header tags, and 10 list items.

Note: When adding a new test, please ensure that your test returns the same HTML string (or equivalent DOM fragment) as the others. Note2: @AndrewF why did you delete the latest two changes? Any comments?
