First steps to using exceptions for error handling
Added two exception classes: one for client errors (= user can fix) and one for server errors (only admin or coder can fix). The web entry point now tries to catch exceptions and show them in the browser. The main code for showing errors in Action class now throws an exception and lets top-level handle it.
