Render floating point numeric attributes with two decimal places of accuracy

[brimoor]

Showing many significant digits for floating point numeric attributes is not useful and takes up a lot of visual space.

This is how ETA renders numeric attributes, which I request we adopt in Player51:

Suggest also moving this one to player51 since this affects Scoop as well.

Side note: that will render anything between 0 and 0.05 as 0.00 - if some numeric attribute is always this small, truncating it may not be useful.

Got it. Let's do "%.2g" instead of "%.2f" for floating point numbers then

(I'll update ETA to match this)

That does have the following side effect, though:

>>> '%.2g' % 234
'2.3e+02'

compared to:

>>> '%.2f' % 234
'234.00'

Is scientific notation desirable for these? Or do we want the %f behavior for numbers >= 1?

Another option:

>>> '%g' % 234
'234'
>>> '%.2g' % .0001234
'0.00012'
