MantidEV copy UB to MD workspace

[Dennis Mikkelson]

After UB has been found/selected/changed, copy it from the peaks workspace to the md workspace. This allows the non-orthogonal axes in VSI.

RE 7247_MantidEV_copy_UB_to_MD_workspace

Added method copySample() to MantidEVWorker. This method is now called whenever the UB is changed. That is, it is called by the "Apply" code for the Find UB, Choose Cell and Change HKL tabs, which are all of the places that change the UB.

NOTES TO TESTER:

The branch name is feature/7247_MantidEV_copy_UB_to_MD_workspace.

To test:

1. Use MantidEV to load and convert to MD the run TOPAZ_6674, which is data from a sapphire crystal. Use Max|Q|=20 and apply the Lorentz Correction.
2. Bring up the VSI for the MD workspace, switch to the scatter plot and turn on the Cube Axes. As you rotate the 3D view around, the axes appear to be at right angles.
3. Use MantidEV to find Peaks using Max a,b,c = 10, Number of Peaks = 250, Min Intensity = 500
4. Use MantidEV find UB Using FFT with Min a,b,c = 4, Max a,b,c = 10 and Tolerance = 0.12. NOTE: When the Apply button is pressed, CopySample is called, as seen on the Results Log panel.
5. Bring up the VSI again as in #2. Now, as you rotate the 3D view, the axes no longer appear to be at right angles. (NOTE: Whether the axes are actually drawn at the correct angles and in the correct relationship to the splatter plot data is a different issue, and is beyond the scope of this ticket, or MantidEV.)
6. Use MantidEV to Choose a cell of type Rhombohedral R. The results log shows that the sample is copied.
7. Use MantidEV to Change HKL. (You can leave the matrix as the identity matrix.) The results log shows that the sample is copied.

Dennis's comment asking if the cube axes are correct is now #7298.
