Added gulp and gulp-less as devDependencies, added gulpfile.js and added
a less task to compile application.less > application.css.
Added gulp tasks for watching browserify bundle and rebuilding when any
dependent modules change, likewise for less. Also added a single-go task
that simply runs browserify on the bundle once and then quits. This is
the default.
Changed npm scripts to use gulp.
Updated README.
Merge pull request #34 from pieterdev/master

Proposed fix for: Insert LESS compilation step into npm make script #20
