Display the beggining of the Alpha value (HOME)

[Gesner Passos]

Muon Grouping Options, the Alpha option was 0.9443364356035816, but when you change to the Home options inside the Detector Grouping, the Alpha shows: 56035816 (because it shows the final part of the number). It would be better showing the beggining, or trunking the data.

Trunking the data is not an option, cause in case we would have a really big value we would see the last digits anyway, so I went with displaying the beginning of the number, so the user will see as much of the value as the size of the interface window allows.

[Arturs Bekasovs]

Moved cursor to the start of the alpha value, so the beginning is displayed.

Tester:

It's pretty much as in the description - just open the Muon Analysis, go to Grouping Options tab, load some grouping file, in Pair Table set the alpha value of the first pair to something long like 0.9443364356035816, return to the Home tab and check that the alpha value box is showing the beginning of the number, and not the ending as it was before.

This works fine for me, but I am unable to pass it since I do not have Git set up correctly. Returning to testing pool until I can get it sorted.
