- changed semantics of ViaTest slightly (setting same value for inputBoth does not change to newly send value as the "FromMqtt-" and "FromRest-" part is not prepended, and therefore it stays the same)

- differentiate between push-send and pull-send

- also fixed bug when using tokens with no type (must be treated implicitly as String)

- rename nonterminal (M)Ros2Rag to (M)RagConnect, and attribute ros2rag to ragconnect
- rename starter to safety
- make receiverstub, receiverstub not depend on safety
- make tests not depend on common (copied proto files)

- Base: inserted DefaultMappings did not account for existing other mappings, but always use type of token
- Base: MqttHandler was not able to have multiple newConnections for the same topic
- Goal: Changed way how last update is handled (now packed into currentStep)
- Goal: Added StartStep
- Goal: Changed wait to be in milliseconds

- Added TestUtils.waitForMqtt

- supported types: int, short, long, float, double, char, and all their boxed variants, and String
- default mapping definitions are NTAs which get reused for every update definition that needs them
- change generated check for not always apply (case for boxed types)
- cleanup parser
