The Un-bodging: Rework to proper backend/frontend

[LunNova]

Currently we're manually copying JSON files produced by the backend to be rendered. This is a bit rubbish.

• Determine whether back-end/front-end should be in separate repos?
  • Split from different branches to different repos
  • Leave as is (separate branches in one repo)
  • Join in to one branch, with better folder structure
• Pick server-side technology for back-end API
  • Jetty + Jackson (already using Jackson)
  • Jetty + Jersey + Jackson
• Change front-end to read from proper API endpoints instead of loading from linked.json

I think we should either split up the branches into separate repositories as the current situation is unsatisfactory and I think that having both parts on the one branch will be far too cluttered.

+1 for using proper API endpoints
