Option to specify whether labels are included in overlap detection for layouts

[maxkfranz]

Including labels can make the graph more spaced out than desired in some cases. Having an option would give more control over the output.

options.nodeDimensionsIncludeLabels : If true, the width of a node is considered to be node.boundingBox().w. If false, the width of a node is considered to be node.outerWidth(). The analogous cases for height also hold.

Uses node.layoutDimensions()
