JavaScript performance comparison

Revision 711 of this test case created

Info

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

@695 - templates compilation moved into bench. suites; - appends indexer to prevent template caching;

@711 move to cdns
