ConvertToDiffractionMDWorkspace: convert one MDEvent per histogram bin

[Janik Zikovsky]

• Take a MatrixWorkspace input.
• Instead of using individual events, use the binning. Add an option for this.
• Convert each spectrum on the fly to an EventList as needed.
• Convert to MD with the existing code.

Note to testers: this is the OneEventPerBin option. Should work on EventW orkspaces and Workspace2Ds. Details in the wiki page http://www.mantidproject.org/ConvertToDiffractionMDWorkspace#OneEventPerBin
