updated etc files as part of network-wide gentoo update
updated rsyncd- change portage tree module name to distinguish between a tree that has been approved for all nodes (gentoo-local-portage) and the portage mirror (gentoo-portage). also fixed rsyncd configuration to ensure xinetd runs the daemon with proper configuration
updated xorgserver pattern- removed fonts since the default system fonts will be used if users don't specify local fonts in the ~/.fonts directory, and added unicode3 USE flag to rxvt-unicode for special character support (vim lightline special characters do not display if this USE flag is not enabled)
removed cron jobs which sync local binary and portage trees to network-accessible directories. These syncs should occur manually when deemed appropriate so that updates can be propogated without worrying about whether or not nodes on the network will use the same ebuilds or not. also fixed repos.conf.erb logic
added packages to different patterns
