added 'getversion.sh' script which simply returns a version string composed out of the versions of the OpenSDE framework and package database delimited by an '-'

Note:

The script is also capable in returning the single version strings of the
framework (using cmdline option '-f') and the version of the package db
(using cmdline option '-p').
