--wip: support unified_inventory, it even seems to have some sort of API now

Example:
worldedit.register_gui_function("worldedit_gui_hollow_cylinder", {

on_select = function(name) print(name .. " clicked the button!") end,

Use `nil` for the `options` parameter to unregister the function associated with the given identifier.
Use `nil` for the `get_formspec` field to denote that the function does not have its own screen.
Use `nil` for the `privs` field to denote that no special privileges are required to use the function.
If the identifier is already registered to another function, it will be replaced by the new one.
