Added absolute path & script minification support

Task now can take 3 options:

    {
        jsDir: "../../js/",
        cssDir: "../../css/",
        minify: true
    }

The first two are directories are where the js and css files are located, relative to the uncompiled html. This helps when paths are listed absolutely.

The third is a boolean to run the scripts through uglifyjs before writing inline.
