Error when petascopedb is not updated to ps9

[Dimitar Misev]

There should be a check which prints an informative message when ps9 is not present, like:
"Petascope can not be started, please update the database to version 9 by running update_petascopedb.sh [—migrate]" or similar:

[Piero Campalani]

Patch applied: changeset:635ce50.
It adds a check on the number of PS9_* tables.
NOTE: every changes to the database will need to adjust this check.
