Reduce theme bundle size by using specific minified libraries

[sacr3dc0w]

What?

In an effort to reduce the size of the theme bundle, I've pointed two libraries to their minified versions.

Screenshots (if appropriate)

Bundle, before history.min.js

Bundle, after history.min.js

Bundle, before slick.min.js

Bundle, after slick.min.js

Bundle, after both history.min.js and slick.min.js

@sacr3dc0w this is amazing. Thanks for all the work on cornerstone theme. Can you please add a change log entry ?

[PreciselyAlyss]

@junedkazi are you comfortable with one of us merging this as it now has a changelog entry?

[junedkazi]

@PreciselyAlyss we plan on cutting a new release today. So will merge it after that is done. Since we don't want to add any new scopes to the testing effort which is based on the current master.

@sacr3dc0w - this is great! can we put them in the webpack.conf.js resolve instead:

    resolve: {
        alias: {
            html5-history-api: path.resolve(__dirname, 'node_modules/html5-history-api/history.min'),
            jquery: path.resolve(__dirname, 'node_modules/jquery/dist/jquery.min.js'),
            jstree: path.resolve(__dirname, 'node_modules/jstree/dist/jstree.min.js'),
            slick-carousel: path.resolve(__dirname, 'node_modules/slick-carousel/slick/slick.min'),
        },
    },

that way the imports can simply be:

import 'slick-carousel';
...
import 'html5-history-api'

seeing as this was already merged, feel free to open another PR
