Re-added voyage's experimental repo, import its key, set to low prio, pinned kernel package and voyage-util to it
Added APT_CACHE option
Allow linux-image-3.10.11-voyage to be upgraded without module warning (see http://voyage-linux.34677.n3.nabble.com/Voyage-0-9-2-missing-RTC-modules-tt4025988.html)
Dont pin linux-image-*-voyage or voyage-util to experimental voyage repo (for now)
Added methods [mount|umount|chroot|install] to deploy-alix-voyage.conf; Fixed defaults for var APT_CACHE
