change a few global Lua variables to be local

Running StepMania with the command line argument of --ExportLuaInformation while the current 5.1's default theme (Lambda) was selected added some seemingly stray Lua variables to the Constants table in ./Docs/Luadoc/Lua.xml. I spotted them here: http://dguzek.github.io/Lua-For-SM5/LuaAPI#Constants I'm assuming num, bPreference, and bCategory don't need global scope, so I added the local keyword where appropriate.
