[WIP] Takes care of some issues Alexander had experienced, part 1
@astigsen 

Changes the appearance of table indices to gray, small and right aligned

Always shows floats and doubles with exactly three decimals

Reloads after cancelling editing to return to three decimals.

Also fixes a mouse over issue (mouse pointer should always change over links)
Naa, there is fallthrough from TypeInt as well.
But the better way would be to not fallthough from TypeInt so the logic isn't needed. That would be more readable.
