Upload Entries as JSON

[kronn]

Puzzletime has an undocumented, inofficial JSON-Interface. The rails controllers accept json on the CRUD-actions. This could be used to upload all entries of a day and then maybe/configurably just open the day-overview to double-check things.

This necessitates adding the credentials to the config and sending them with every request (or keep a cookie an send that).

A simple solution would just upload the local entries. A more sophisticated, sync-like behaviour would first retrieve a list of existing entries of the day in question and only upload new ones, outputting a summary of what has been done and what the current state is, so that I do not need a browser at all.

A good first step to this is IMHO to just upload blindly and create follow-up issues for further improvements.
