MoreSecurity, wakein.[hm]: Removed authenticated wake timer setting
code: it was unneeded and incomplete, but remains in case it needs to
be resurrected later.
PSPowerManager.[hm]: removed -authorize, exception, references to
MoreSecurity and wakein tool (-_execWakeToolWithRequestDictionary:).
Simplified writeDataProperty by using IOConnectSetCFProperty instead
of IOConnectSetCFProperties. Fixed logic error in override which
caused timer not to be set as needed.
PSTimer.m: Display alert panel if errors encountered while setting
wake time.
