Feature/geppetto client#35

[jrmartin]

Changes needed after dependency changes in openworm/geppetto-client#35 .

• Webpack dependency upgrading from version 3 to 4, webpack needs now the flag '--mode' to run. Right now is has been set to '--mode none', the options.

• Uses mini-css-extract-plugin instead of extract-text-webpack-plugin as css-loader.

• webpack.optimize.CommonsChunkPlugin becomes splitchunks in webpack 4.

Build folder file output using CommonsChunkPlugin in webpack 3 vs using SplitChunksPlugin in webpack 4. (Webpack 3 CommonsChunkPlugin on Left vs Webpack 4 SplitChunksPlugin on Right) Main visible difference is that main.bundle.js got reduced and is now 11.2 kb instead of 6.65 MB and that common.bundle.js size increase and is now 7.26 mb instead of 1.69 mb.

After changing some settings in commit https://github.com/openworm/geppetto-application/pull/15/commits/38875627b4a3598d5d12405f7afbf53c0e77262c, the main.js and common.bundle.js are now similar size to what they were in webpack 3.

Passing travis test https://travis-ci.org/openworm/geppetto-application/builds/562163182

@jrmartin I merged another PR first and this now has conflicts, can you resolve them?

[jrmartin]

@tarelli Conflicts have been resolved, passing https://travis-ci.org/openworm/geppetto-application/builds/562163182

I tried it on windows with the last version of npm and the install worked. Couldn't go further due to a problem with the build in windows (see #19)

[tarelli]

@filippomc #18 seems unrelated?

[filippomc]

@tarelli yes it's a problem also with the development branch.

I think this is the issue you are referring to https://github.com/openworm/geppetto-application/issues/19
