Change 'Zoom to Fit' margins and add 'Zoom to Objects' 

CHANGED: The margin used in 'Zoom to Fit' is now 2% instead of 10%.

ADDED: Added 'Zoom to Objects' to Eeschema which does not include
the page and border in the bbox calculations.

CHANGED: Removed pre-existing code that tweaked the center to account
for the scrollbars.  It actually made the view off center.  Removing it
results in perfectly centered zooms.

Fixes https://gitlab.com/kicad/code/kicad/issues/5145
