Architecture Desing Diagram (#1496)

We use the software for education purposes to create illustrations for example System Design documents in one of our courses. The software provides most diagrams we require, however we miss adequate diagram types to Architecture Design Overview (featuring visually self explanatory bitmaps of "user", "computer", "database", "client", "cluster", "connection", "cloud", etc.). So far we used other tools for this purpose, but it would be nice to have such diagram support in the Standard Edition.
