So DatabaseBuilder.Settings has all the getters for code looking to read
the configuration that has been set. So DatabaseBuilder now just has the
setter methods.
Use DatabaseBuilder.settings() to access the settings and read the config
that has been set.
With this, people can depend on ebean-postgis (the composite) and get all the
dependencies they need (which is ebean-platform-postgres + ebean-postgis-types
+ others).
This should just make it easier for people in that currently we need both
ebean-postgis + ebean-postgres which isn't obvious enough.
