ubuntu: Added progress notes and isues
debian: Changes a wrong env variable from INSTALLCHROOT to INSTALLDIR
Exported DISTRIBUTION and TEMPLATE_NAME from Makefile

ubuntu: Refactored and split major functions into own shell script

uptopic building
trusty building with pre+post systemd hack (using utopic systemd packages)

Added better mount / umount logic
Added snapshots
Major shared functions are in functions.sh
Added experimential systemd-nspawn instead of chroot

systemd-nspawn can be enabled with USE_SYSTEMD=1 enn var
still needs work on perfecting the mounted binds needed

Added ability for build pre/post scripts to reside in $SCRIPTSDIR/$DIST directory
Tests reworked for above
ubuntu:  Added files to fonts and display issues (same issues debian had)
