Additional script types to be compressed as HTML

```
It seems that the script type 'x-jquery-tmpl' won't be used much in the future
as jQuery tmpl plugin has been abandoned [1] some time ago. It would be good if
'text/html' and 'text/template' were added to the script type check, as they
are the two most commonly used alternative types for JS templates.

If you accept patches I'll be able to do this sometime this week.
Thank you.
