Update to domoticz spk&cross (rev 1812)

Boost patch did not seem to be necessary anymore, so removed
updates to Makefiles/PLIST of cross and spk for rev 1801
dsm-control.sh updated to correctly start/stop/status domoticz
installer.sh updated to create a /var directory
Oh well, my mistake, you do need them in the install target if domoticz does not do that for you.
