Subject: Empathy: Add a new /answer route to accept answers from a user
X-Git-Url: https://git.cworth.org/git?p=empires-server;a=commitdiff_plain;h=d4cda1d79dd27aea818e1e35f30bcc3d745208a3

Empathy: Add a new /answer route to accept answers from a user

This is the bare minimum, simply storing the answers. Going forward
we'll want to expand this to inform players when another player has
submitted, etc.
