Added three new tools to the WKEY menu for Armatures in EditMode/PoseMode. These add .* extensions to the names of selected bones based on their position in 3d-space on the axis considered by that tool. The current naming schemes are based upon the extensions I normally apply. Some people may have slightly different preferences though. There is one for: * Left-Right names (along x-axis) * Front-Back names (along y-axis) * Top-Bottom names (along z-axis)
