Setup better support for slow internet connections

[youngkidwarrior]

Most the images are gigantic pngs.

• Change them to svg images

• Load iamges progressively, like the entry page image

• Lots of unused imports can be taken out, (should be fixed with a proper linter)

• We can probaly lazy load some elements, like the svgs in contacts

• the wrong font is displayed when connection is slow, make sure fonts are loaded first
