Minify CSS and Javascript when building a release

[azaozz]

We can add a script to trac that would minify both js and css on release, excluding already minified files like jquery.js and tiny_mce.js. The css would shrink about 20% and the js about 30-35%.

Went in different direction, instead of minifying at build time all files have .dev.js (non minified) and .js (minified) version.
