== Automatic Bone Extension Adder ==

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)
