Remove unused D-Bus interface of the alarm daemon
That provided 4 methods: - quit() is already exposed via KDBusService, and isn't really necessary as we have no transient state anymore, so just terminating the process is safe. - forceAlarmCheck() calls a method that runs every minute anyway. - dumpDebug() just prints a value from the config file, so you could just look there... - dumpAlarms() is the only one actually doing something, but it's not dependent on any state or functionality of the alarm daemon itself, a simple test program running stand-alone could do the same if necessary. Ie. there is no loss of useful functionality here I think, even for development. Instead this further simplifies the code.
