Refactor data handlers + misc fixes

This refactors the data handlers into a more standard/understood model-like architecture, to prepare for a new, more robust config system.

It also fixes a problem with creating new Notes and uploading new Photos via the web interface (related to #58).

Finally, it speeds up docker builds by sending in less files, which aren't necessary or will be built anyway.

This is all in preparation to allow building #13 more robustly.
