Add support for lessOptions.
Fix less options test.
Add Promise and System to jshint globals.

Sublime text won't stop complaining about that.
Use a flat object to set less options.

This change removes lessOptions.parse and lessOptions.eval. Thanks to

options, yay!
- Allow to have custom paths option
