ENH: additional method for switching error throwing on/off (issue #552)

Browse Source 
- error::throwExceptions(bool) returning the previous state makes it
  easier to set and restore states.

- throwing() method to query the current handling (if required).

- the normal error::throwExceptions() and error::dontThrowExceptions()
  also return the previous state, to make it easier to restore later.
