additional options for translation

[kof]

Sometimes you have a string combined with some html or data which don't have to get into translation.

// template
{{e({ opentag: '<b>' , closetag: '</b>'}) "my template is #opentag nice #closetag"}}

// translation string:
my template is nice

// html output
my template is <b> nice </b>

I'd rather use something similar to printf()

{{e("<b>", "</b>") "my template is %s nice %s"}

or extend String.prototype

{{e "my template is %s nice %s".format("<b>", "</b>") }}
// coffescript style:
{{e "my template is #{open} nice #{close}".format({ open: "<b>", close: "</b>"}) }}

the first one is also fine, but extending native prototype is a bad idea, because it will affect the whole env.
