fix for #453, Incompatible handlebar syntax

[soenkeschnoor]

As suggested by yourself in #453, this should ignore the contents of this script/style tags.

Hope it helps. :)

Looks very nice. Minimal changes, for maximal effect. Can you wrap your lines to not be super long and maybe modify or remove the comments currently at the end of those long lines?

[soenkeschnoor]

Sure. No problem.

Also should be supported text/ecmascript, application/javascript, and application/ecmascript:

With version, like application/javascript;version=1.8 (just a note, currently works fine with text/javascript;version...):
https://developer.mozilla.org/en-US/docs/Web/JavaScript/New_in_JavaScript/1.8
And legacy things like application/x-javascript:
