Get python working in MantidPlot debug build

[Russell Taylor]

(In [4822]) Replace boost_python debug libraries with ones linking to python debug build. Changes to PythonAPI project file to link everything correctly. Now python scripting works in my debug MantidPlot! (if I comment out a couple of lines in PyAlgorithmWrapper.cpp) Re #1305.

[Russell Taylor]

Works so long as you don't have any python algorithms being picked up (in which case it crashes on start-up).

Here's the stack trace. Note that the kill() method also calls Py_DECREF.

(In [4959]) Fix issues with MantidPlot crashing in debug mode when running Python code that raises an exception. Re #1305

[Nick Draper]

Moved to verify state

[Michael Whitty]

step for reproducing bug

[Michael Whitty]

MantidPlot Debug causes an unhandled exception due to:

Fatal Python error: PyThreadState_Get: no current thread

Where no such error occurs in release.

Reproduction steps:

Custom Interface->indirectAnalysis, elwin tab, insert file given above and -0.1, 0.1 in input boxs then click run.

[Janik Zikovsky]

I've been able to run Python algorithms in a debug MantidPlot under Ubuntu. Pyhon scripting works too. Elwin does not run to completion, but RebinSuggest (for example) runs fine; so this is not a general Python in MantidPlot debug problem. Perhaps a ticket for Elwin should be made.
