Eventsystem for Cadwork

[bastiannispel]

Cadwork is a single threaded Application. In order to work with data that comes from external sources (/endpoints) and needs to be processed via the cadwork API, it's necessary to actively block the current CW thread. If there were events we can subsribe to in order to block when it's really required we could improve the user experience a lot and ensure more stable solutions for data transmission.
