Stack performance and bundle optimization (Lighthouse)

[march08]

• Resolving some issues regarding to the bundle size Amcharts increasing bundle size dramatically #39 , though still not perfect. Nothing more can be done at this moment tree shaking does not work - bundle size is huge amcharts/amcharts4#82
• code splitting - now every page loads it's own assets Optimize bundle size #6
• fixed some issues with assets loading (images and others)
• accessibility fixes, incl Disable autocomplete and spellcheck on search bar #22

Chunks before:

Chunks after:

Old Lighthouse measurements (incognito mode, default settings for mobile testing):

New Lighthouse #15 #6

There can still be some improvements done in the performance department

• facade load of third party scripts
• reduce sizes of some image assets (world map is eating quite a bit)
