Move code for debugging capabilities in Ohm to Gramada

[codeZeilen]

The following method should be maintained by Gramada as Ohm does not require it:

OhmGrammar>>#skipSpaces: state

    | result originalPosition anInput originalFailures |
    anInput := state inputStream.
    originalPosition := anInput getState.
    state isSyntactic: false.
    originalFailures := state rightmostFailure.
    state rightmostFailure: OhmFailureDescriptor new.

    [ originalPosition := anInput getState.
      state pushBindings: OrderedCollection new.
      #ohmDebugging withoutLayerDo: [
      result := (self ruleNamed: #space)
                eval: state].
      state popBindings.
     ] doWhileTrue: [result].

    state rightmostFailure: originalFailures.
    state isSyntactic: true.
    anInput setState: originalPosition.
