Title: Defining ACLs in pg_hba.conf

This is to allow users to define more granular ACLs in pg_hba.conf. Users can specify lists of strings to act as items in the ACLs, such as ```ipv4acls => ['hostssl jdoe all 192.168.0.0/24 cert']```
There are IPv4 and IPv6 versions, more for organization's sake than anything else, since IPv4 and IPv6 should be able to be mixed without a problem.

The README.md file was also modified to present an example of how to define ACLs.
