Allow minifying HTML before compiling templates

[tigerclaw-az]

I would the option to minify the HTML that will be compiled so that I don't get any extra newlines and comments. I cannot use 'htmlmin' because it does not handle template formats.

I would say to minify mustache instead of html. Because there are spaces between inline-block nodes that leads to moving last inline-block element to the next string in lists.
