Parameters in scenario's

[henkschuurman]

Please add a new option to use parameters in a scenario:

Deze halte is vervallen voor lijn 24 tot [eindtijd]

When the scenario is planned a pop-up will appear to fill in [eindtijd] and that value will be filled in the actual message. More advanced also the format could be included then [eindtijd|tijd] or [einddatum|datum] of [info|tekst](where the first is the prompt and the second the required format)
