Add presets, templates to .mod, rename aetemplate

The module generating script was missing the bundled attr presets and
the custom AETemplates required for our custom nodes, without which Maya
kind of randomizes the I/Os in the node editor. Added this, plus icons
location via XBMLANGPATH, and MAYA_SHELF_PATH for the future custom
shelf.
