replace any additional slashes in the DOOCS property name by a dot, since DOOCS does not support additional slashes in the names.

removed all uses of the ProcessScalar class and replaced it with the ProcessArray (ProcessScalar will be removed from the CSA soon)

moved to the "ProcessVariableAccessors" branch of the control system adapter, which unifies the interface with DeviceAccess

added the include emptyServerFunctions.h to tests which would not need it, just to allow linking all tests in the same way (against libEqServer)
