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).

lib/phpPgAdmin.login.php.diff: public_ user's password message: Print as its own message instead of appending it to $msg. Print it before any error message so it always appears at the top of the page.

root Makefile: PostgreSQL: phpPgAdmin: Edit config file to allow passwordless logins. Edit login page to fill in public_ as the default username and add a message to leave the password blank for that user.
