moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

Makefile, schemas/.Mac.conf: upgraded to PostgreSQL 9.3, which is needed for proper exception parsing in the auto-re-create-views functionality. this also removes the Mac 10.8 Mountain Lion quirks, such as renaming the postgres user to _postgres (which messed everything up, but is now back to normal).

bugfix: schemas/pg_hba.Mac.conf: made same change for Mac as was made for Linux in r11451

bugfix: schemas/pg_hba.Mac.conf: use new postgres ident map instead of changing user to _postgres, because the DB user is still named postgres

bugfix: schemas/pg_hba.Mac.conf: changed postgres to _postgres for OS X 10.8 Mountain Lion

schemas/pg_hba*.conf: removed trailing whitespace

schemas/pg_hba*.conf: allow the bien group to access all databases, including test (on the Mac). note that this does not grant access to the vegbank DB on vegbiendev, because that is owned by postgres.

Makefile mk_db, schemas/pg_hba*.conf: Added passwordless public_ user with access to just the database schema. Note that in PostgreSQL, only users with explicit GRANT permissions on a table can read data in that table, but all DB users with a login can view all table schemas.

schemas/: Synced pg_hba.conf and pg_hba.Mac.conf's bien entries, which adds phpPgAdmin support (template1 access) on the Mac and bien_read access on Linux

schemas/pg_hba.Mac.conf: Allow access to the bien group rather than just the bien user, which will include bien_read

schemas/pg_hba.Mac.conf: Fixed bug where also need to allow password-based logins from the same machine, in order to work with pgAdmin

schemas/pg_hba.Mac.conf: Fixed bug where needed ident entry for postgres superuser

schemas/pg_hba.Mac.conf: Changed to match schemas/pg_hba.conf

Added schemas/pg_hba.Mac.conf
