Node Wrangler Update

I rewrote the alignment function to be more pretty and user friendly - just select some nodes and press Shift+Equals to lay them out neatly next to each other. I also did some minor tweaks to the drawing code of the Lazy functions (Alt+RMB drag, Ctrl+RMB drag, Ctrl+Shift+RMB drag).Node Wrangler is in Blender by default, so you'll get the updated version in Blender 2.75 or from the buildbot - or just download it here and install it again :)<strong>Commits:</strong>
