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).

bugfix: backups/fix_perms: just make the backups themselves private, since the other files are in svn, and their permissions should match their accessibility through Redmine

backups/fix_perms: Removed world read permissions from backups dir. Note that this will require superuser permissions to view archived backups on jupiter, because the bien group is not set up with the same members as on vegbiendev. (On jupiter, it contains only stri,regetz,donoghue,naiamh.)

Added backups/fix_perms
