Export lua data

[ivinokur]

I'm trying to export some game data with Export.lua.

I have detect a bug with export PCA panel data, when I call (ex.)

panel:get_argument_value(235) -- PCA Button 1

for getting a state of a button (when displayed "S") I was getting 0 value all the time also after click this button from cockpit with a mouse, except a time when I'm using a keyboard.
