perf: Smaller build 1

[ptbrowne]

Bigger issue : #926

Baseline: 2421ko

• Remove duplicate lib via webpack aliasing : 2317ko

• Do not bundle all d3 inside build : 2179ko

Some other ideas:

• remove the Fetch polyfill (it is no longer needed for the browsers we support)
• use lazy loading for the graphs libs
• redux-raven-middleware and raven.js seems to load the same files: are both necessary?
• try svgo on icon-collect-account.svg

Cozy Authentication build ? Why is it so big ?

It embeds 65ko of CSS from cozy-ui, and some stylus things

I don’t see the interest in minifying image, it should be webpack that handles this, no ?

Tomorrow when we add another image we forgot to minify it, ...

Well, there are some pros and cons to do that. For example, minifying images can take a lot of time and make the build really slower.
