Add legacy DB and upgrade info to bin/version.pl

Before version.pl only displayed the database version
of a TUSK 4.0 database. Now it displays legacy information
if on an older database install.

Add to version.pl to show if upgrades are available.
Add word `schema' to bin/version.pl output
Remove install/scripts/create_school.pl

Deprecated in favor of install/bin/baseline.pl
with --create-school option, which does more robust
error checking and can be run multiple times without
harm.
