fix: MemoryNameSystem waitForServer: missing call to processOnce() whenever a new server connects to the MNS

Add proper Image type to Aron and improve visualization in MemoryViewer + some ArMem refactorings

See merge request ArmarX/RobotAPI!193

Both SimoxUtility/EigenStdVector.h and RobotAPI/libraries/core/EigenStl.h are no longer needed. Removing usages
