LDEV-2484 Fixed monitor (only 1 learner progress showing issue) - due to Support Activity not being handled by the drawing process (since the Support Activity REFERENCE_ACTIVITY_TYPE activityTypeId 15 was not managed in the conditional statements) resulting in the next learners not being draw.
LDEV-2343 Fixed issue with alerts and starting connection, problem now fixed by waiting till all alerts are closed (for no mic or camera) and then the connection is started. Put used image resources in src assets folder. Commit for 2.3
