Improve error reporting from algorithms in multithreaded loops

[martyngigg]

This issue was originally TRAC 7446

http://trac.mantidproject.org/mantid/ticket/7325 & http://trac.mantidproject.org/mantid/ticket/7400 raised the issue that error messages thrown from multi-threaded loops can be misleading. They always end with something like:

PeaksInRegion-[Error] PeaksInRegion: error (see log)

where PeaksInRegion is the algorithm name.

The problem is you are generally looking at the log reading that message and there is no more information anywhere. We should try and improve the error reporting from OMP loops by maybe storing the last exception thrown and rethrowing it or at least store the message and remove the parts about seeing the log.

This doesn't need to be done by me so I'm leaving it for the general maintenance pool.

Hasn't been address and very low priority.
