Disable popups when draw toolbar is active.

[JeffJacobson]

Currently, if a layer with popups is visible, the popups will occur as the user is drawing geometry with the Draw toolbar.

• When the draw toolbar is activated, popups should be deactivated.
• Popups should be reactivated when draw toolbar is deactivated.

Possible solution

• When the web map has been created, loop through all of the layers and looking for feature layers.
• When the draw toolbar is activated, disable mouse events for the feature layers.
• When the draw toolbar is deactivated, re-enable the mouse events for the feature layers.
