Add probe mode to Splatterplot view

[Michael Reuter]

The Splatterplot view needs to have a way to trigger the VTK probe filter. This will be used to pick peaks in the display and retrieve the coordinates. Those coordinates will be passed onto a service that will then handle the information in an appropriate manner.

Refs #7148. Adding pick mode for Splatterplot

Can currently add and remove the VTK probe filter, but nothing else.

Refs #7148. Trying to hook up pick mode with coord retrieval.

This doesn't seem to work yet as I can't find the way to get the coordinates. Also, the event filter seems to trip off if you switch away from the window and go back.

Branch is ​here.

To test:

1. Start MantidPlot and load a TOPAZ run, such as TOPAZ_3132_event.nxs, and convert it to an MD workspace. The quickest way to do this is to bring up the Interface: SCD Event Data Reduction (SEDR), and use the Browse button on the first form to select the event nexus file. Set the Max |Q| to Map to MD to 25, and turn on the Lorentz Correction. Press the Apply button to both load the file and convert it (properly) to an MD workspace.
2. Switch to the Find Peaks tab and hit Apply
3. Switch to the Point Info tab and move window aside
4. Open MDEventWorkspace in VSI and switch to SplatterPlot view
5. Enter pick mode by clicking the Pick Mode button
6. Place the mouse over peak and hit the p key
7. Observe that information is displayed in the SEDR Point Info tab
8. Exit pick mode by clicking the Pick Mode button

[Owen Arnold]

Apparently this branch has not been merged into develop. This is probably because Martyn recreated Develop from Master since you merged the branch in last time.

Could you please run git checkbuild (or equivalent git commands) to merge this branch into develop so that I can continue with testing.

[Owen Arnold]

So I merged this branch into Master anyway to test it, and it's very nice. I did however manage to trip-over an exception that I think we could be better handled (see attachement). Pressing continue is OK, but the dialog is not desirable.

[Michael Reuter]

Please open another ticket on this issue because the probe mode is actually decoupled from the thing (SEDR) that is handling the data. The VSI just throws the coordinates over the wall.
