Message:

added argument completion function for active gui sheets.
TODO

a) there should be a better way to read back values from lua (i.e. by using LuaState instead of plain lua.h functions)
b) it shouldn't be necessary to call lua anyway to get the active gui sheets. the GUIManager should always know this.
