KSMServer: improve suspend code

1. Some code deduplication. Suspending is now handled via the public method `suspend(int)` which is DCOP-accessible and maps SuspendType values to corresponding TDEHWLib TDESystemPowerState values, and the internal method `suspendInternal(int)` which performs the chosen suspend and optionally locks the screen beforehand.
2. Options are now read from power-managerrc on startup and stored in memory to avoid reading the configuration file every time a suspend is requested.
3. SuspendType is now a member of KSMServer class (instead of KSMShutdownDlg)
4. A new DCOP-accessible method `suspendOptions()` returns a TQStringList of all available suspend options.
