Doc: port change with Browser-Sync

[bcldvd]

First thing I wanted to do after generating my app with this generator was to change the port :/
I thought I'd add it for others like me :)

As said here https://github.com/Swiip/generator-gulp-angular/blob/master/docs/how-it-works.md#gulpconfjs, we are very thrifty about the conf.js file as we don't want to come back to a big json file like with Grunt.

I don't see why it's needed to deport this conf from server.js to conf.js. It can be kept in server.js.

What we can do is to have better doc about configuring BS. If you turn your PR into a doc update, it would be highly appreciated.

Changed it into a doc update :)

Thanks :) Would it be to much to ask if you could turn this into something a little more generic about "all" BS options including a link to http://www.browsersync.io/docs/options/ ?
