Merge repositories

• Merge in teamkogg/hovercardslanding
• Merge in teamkogg/hovercardsserver
• Merge in teamkogg/hovercardsshared
• Rename hovercardsextension to hovercards

Have one repository for hovercards.

This would let us keep the versions between extension/landing/server coupled, have a very simple development environment, share fonts/assets between all of them, way simpler pipeline, etc. All the pains of having the repos depend on each other would be gone, as well.

Now that cameronroh/hovercardslanding is using webpack, it should be trivial to move it into another repository.

So this is done! I have a few more things I wanted to do here, but they work with #17 & #18 so I'll do them as I go.
