physikerwelt 5c12ed983f Remove useless debug functionality
* MathDebug was intended to provide advanced debugging functionality
  for the math extension. However, the interesting debugging and
  logging feature never made it from the debug branch to the master.
* The current debug functionality is mostly useless. Only some values
  are written to memory and never used thereafter.
* This change moves the existing functionality to the MathSearch
  extension and introduced the required hook for that.

Details:
* $wgMathDebug is removed
* A new Hook MathRenderingResultRetrieved is created
* The math rendering object is printed to the svg error
  page if wgDebugComments is active (instead of wgMathDebug)
