This updates Actor classes, class methods, and Enums listed in the
bundled copy of Lua.xml to be current.
I used the command-line arg --ExportLuaInformation, to generate a wholly
new file, then manually removed some methods (e.g. literally numbered
PlayerOptions methods ported from notitg, CamelCase aliases of
spline-related methods) to keep previous manual modifications intact.
This doesn't touch GlobalFunctions in Lua.xml; those need further
review.
