Remove comments from javascript files in production environment

[Seikyo]

This PR removes comments from compiled javascript files in production

Please let me know if this was intended to be the default behaviour I will work on implementing a method to allow default options to be overridden

Hi @Seikyo,

Isn't that the default value for UglifyJS (cf. https://github.com/mishoo/UglifyJS2#output-options)?

There is another open issue (#15) kind of related to how comments are handled during minification. From what I read in it the only comments left should be the ones containing @licence or @preserve, which is an intended behavior.

Hi @Lyrkan

After some research here is the default value for uglifyJS comments : /^\**!|@preserve|@license/

I think you can cancel this PR as it is indeed the expected behaviour. It would be a better idea to allow overriding uglifyJsPlugin as suggested in #15 and will resolve my issue.

For information, with the options comments: false all comments are properly removed.

Edit : Closing the pull request myself
