Hide exception type name for custom exceptions

[ombre42]

From the user guide:

Starting from Robot Framework 2.8.2 it is possible to avoid adding the exception type as a prefix to failure message also with non generic exceptions. This is done by adding a special ROBOT_SUPPRESS_NAME attribute with value True to your exception.

public class MyError extends RuntimeException {
    public static final boolean ROBOT_SUPPRESS_NAME = true;

Good catch! Added an issue to PythonRemoteServer too:
robotframework/PythonRemoteServer#6

@pekkaklarck Thanks!
I did not notice it when 2.8.2 came out because it was not in the release notes. It was implemented for a Telnet library issue fix.
