Change a system's Virtualmin license key

This program updates all files that we know contain a Virtualmin licence key
with a new serial and key. The two required parameters are C<--serial>
and C<--key>, which of course are followed by a valid Virtualmin Pro serial
number and key code respectively. If these are not actually valid, the
program will refuse to apply them, unless the C<--no-check> flag is given. If
GPL detection must be disabled use the C<--force-update> flag.
