This provides a simpler js template engine than JsTemplate. It has been

optimized for the way we do internationalization with JST before
and is about 4 times faster (average 4.8ms vs 22.8ms) for the history
page.

The syntax for this is very similar to JsTemplates. It uses the
attributes i18n-values and i18n-content which worls like jsvalues and
jscontent except that it does not allow arbitrary expressions.

BUG=None

TEST=All UI pages should work as before
