WARemoteDebuggingWalkbackErrorHandler>>open: relies on breakpoints firing to debug continuations

[dalehenrich]

When native code is enabled in the GemTools (or tODE) client the breakpoint probably won't fire and that leads to interesting and unfortunate breakage while trying to debug the continuation.

At a minimum the following code:

  action == #'debug'
    ifTrue: [ 
      | meth |
      meth := self class lookupSelector: #'remoteBreakpointMethod'.
      meth setBreakAtStepPoint: 1.
      self remoteBreakpointMethod ]

should be changed to:

  action == #'debug'
    ifTrue: [ self halt ]

We could get fancier if we need to continue to use breakpoints ...
