python 'mergePlots' command is broken

[Russell Taylor]

Try doing, e.g., plotBin(workspace('ws'),(0,1)) (which will call mergePlots underneath).

You will wind up with a graph with only the first curve on it.

[Russell Taylor]

OK, this is specific to plotBin, because the qtiplot table that's backing up the curve gets deleted when the original graph window is closed in the mergePlots method. It might be better if the table 'belonged' to the curve rather than the window.

For this specific case, though, I think the best fix is to modify MantidUI::plotBin to take a list for bin numbers rather than calling it multiple times from python if more than one bin is given to the python function. This would leave the mergePlots issue as very much a corner case (I think mergePlots should be deprecated anyway).

Fix plotBin to use a list of bins directly. Refs #5847

Also raises an error for multiple workspaces that don't work at all. As the ticket suggests mergePlots needs deprecating and plot commands upgading to work with multiple sources correctly.

Tested with the following plots

plotBin("GEM38370",(0,1,2,3,4))
plotBin("GEM38370",(1,2,3,4),True)
