Update to domoticz spk&cross (rev 1853)

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
No that was a mistake actually, don't do that. I couldn't find my comment to ammend it after I noticed I was wrong.
