Adds support for PostgreSQL which resolves dani-garcia#87 and is ment…

…ioned in dani-garcia#246.

This includes migrations as well as Dockerfile's for amd64.

The biggest change is that replace_into isn't supported by Diesel for the
PostgreSQL backend, instead requiring the use of on_conflict. This
unfortunately requires a branch for save() on all of the models currently
using replace_into.
