Ability to resize mesh viewport to bounding box of geometry on Update

[Marc Syp]

[4/8/2015 3:15 PM] Marc Syp: currently I'm doing a multi-select that is rescaling the meshes to more or less fit the geometry to the viewport as the selection changes [4/8/2015 3:15 PM] Marc Syp: but if you zoom into a multi-selection and then select something else, it remembers the viewport zoom level as a global value [4/8/2015 3:16 PM] Marc Syp: and you end up way zoomed in or way zoomed out [4/8/2015 3:16 PM] Marc Syp: would be great to reset the viewport on a value change

Should be a toggle so that you can also set up the bounds once and then let it ride.
