Investigate moving to Babel 7 when it releases

FYI CRA has already got a pre-release with a Switch to Babel 7

I have this mostly working locally.

However we need to first:

update to Jest 22 (since it adds babel 7 support, by making babel-core a peerDep instead, so we can use the babel-core@^7 shim) - there were strange test failures on #770 which I've managed to resolve - PR #823 now opened
fix the Preact linting config (#821) since updating to babel 7 means likely dropping use of babel-plugin-jsx-pragmatic (since it tries to pull in a babel 6 plugin; and isn't very maintained) - and without linting working properly, people won't be warned about the need to add the explicit preact imports
