---
--- exceptiontest <location> <errortype>
---
--- location has to be one of:
---   * mapgen:          cause in next on_generate call
---   * entity_step:     spawn a entity and make it do error in on_step
---   * globalstep:      do error in next globalstep
---   * immediate:       cause right in chat handler
---
--- errortypes defined are:
---   * segv:            make sigsegv happen
---   * zerodivision:    cause a division by zero to happen
---   * exception:       throw an exception
