Rename file to Mote-Globals.  Separate instance for users will be created.

--HG--
rename : UserGlobals.lua => Mote-Globals.lua
Change reference to match name change.
Set up functionality to load user-specific versions of repository files:
job_gear.lua, and user-globals.lua.  If they don't exist, load the default
ones from the repository files.
Change main set definining function name from self_initialize to init_gear_sets.
Check for user job_gear.lua include to use for loading gear sets. Only init
gear sets in local file if the secondary file isn't found.
Move setting the default macro page into init_gear_sets, so that users can
put their own values in job_gear.lua and not have it overridden.
Same changes as above for pld and template files.
Move local binds into init_gear_sets so that they're isolated from custom
user binds if the user version is loaded instead.
Add an unload_user_gear function call on file unload.
Change function name.
