Add an option to turn off zooming to intersected features

[ChrisBuscaglia]

Currently if you have a large intersecting feature, you may want to turn off zoom level.

If the user specifies 0, turn off zooming

[pLeBlanc93]

Since 0 is a valid zoom level, can this be changed to a negative number?

There are three different zoom scenarios I can think of:

• always zoom to a specific scale after clicking (ranges from 0-23)
• "zoom to layer" on intersecting feature (-1?)
  • what if it's not intersecting?
• never zoom at all (-2?)

[ChrisBuscaglia]

I agree that 0 is a valid zoom level - but -2 may not be intuitive for the user? Mike - can we place some hints in the configuration?
