User facing changes

• Breaking: Renamed the main class from com.digitalasset.scribe.Main to com.digitalasset.pqs.Main.

Postgres connection

• Breaking: Renamed the application name property in the Postgres connection from scribe to pqs.

Configuration

• Added support for environment configuration with PQS_ prefix (e.g. PQS_TARGET_POSTGRES_HOST).
