Make the property a running version or turn it off as the running
version. A property that is made a running version will preserve the
current state in such a way that it is retrievable by a future call to
'recoverRunningVersion()'. Additionally, a property that is a running
version will resolve all functions prior to returning it's property
value. A non-running version property will return functions as their
uncompiled string representation.
Parameters:
runningVersion - flag whether this property is a running version
Take the given property object and merge it's value with the current
property object. For most property types, this will simply be ignored.
But for collection properties and test element properties, more complex
behavior is required.
Parameters:
prop - the property object to merge into this property
