Removed unnecessary icons from the toolbar (performed the same actions of entries already in the menu).
Proper handling the export of the list.
Updated the .po files.
Before this change, if you try to save state to a bound which already
does something as a UI button, it will save state there and then
immediately execute the bound action (sometimes it would not happen).
So, if you have state to P, with default button it would pause the game
immediately after saving state (except sometimes it would not).
