Update to new time-related properties
SAREF now includes new properties to specify more clearly the time in which some phenomenon happens. One of them was already used in SAREF4WATR with the same definition.
PROPOSAL:
* Replace s4watr:hasPhenomenonTime with saref:hasPhenomenonTime.
* Replace saref:hasTimestamp with saref:hasResultTime.
Changes have to be performed in the OWL code, TS, diagrams, documentation, tests and examples
