[Feature] Minify output

[lonix1]

It would be very helpful if the razor compiler would produce minified output.

The simplest approach would be to

• remove whitespace between elements (e.g. convert double spaces to single space, trim trailing/leading spaces)
• remove whitespace within attributes (e.g. class)

A full-featured minifier can do much more than that - but I propose that the basics above would be good enough.
