Info "stats" looks horrible (since numpy 1.14)

With numpy 1.14+ much of the formatting got much better, but info('stats') is not one of them:

t = QTable([[1.0, 1.1, 1.2]])
t.info('stats')
<QTable length=3>
name        mean                std         min max
---- ------------------ ------------------- --- ---
col0 1.0999999999999999 0.08164965809277258 1.0 1.2

where before it was

<QTable length=3>
name mean       std       min max
---- ---- --------------- --- ---
col0  1.1 0.0816496580928 1.0 1.2

Basically, the rounding rules changed. In the doctests, it was a change like in mean that made it look horrible, but in this example one sees it can be bad without too. I think we basically need to set some default format for columns that uses a sensible number of digits.

Now that we only support numpy versions that have this change (as well as we can change this now in the new LTS more easily than waiting longer along the road when downstream should support multiple things), it would be nice to come up with a solution for this.

Yes, good change! Closing…
