Mustache Escaping Flag

[stellarpower]

Add boolean parameter to mustache to control whether escaping of special characters is performed or not.

I am working with plain files, YAML, etc., and the HTML escaping that the Mustache_Engine is set up with causes problems here.

It might be desirable to expose further finetuning instead of making it a boolean, leave that up to you.

I've done basic tests but not written any testcases etc.
