v1.5.1

Plugins:

• #351 layouts.forceLink Layout pulls nodes too close together

Rendering of node border has been changed (breaking) with new settings:

• Rename borderSize to nodeBorderSize
• Rename outerBorderColor to nodeOuterBorderColor
• Add nodeBorderColor, nodeOuterBorderColor, nodeOuterBorderSize, defaultNodeOuterBorderColor
• Add nodeHoverBorderColor, nodeHoverOuterBorderColor
• Add nodeActiveBorderSize, nodeActiveBorderColor, nodeActiveOuterBorderColor, nodeActiveOuterBorderSize, defaultNodeActiveOuterBorderColor
