Code review comment for lp:~widelands-dev/widelands/bug-536489-dropdown

This Drodown is missing a feature found in all normal GUIs:

when you click outside the dropdown it will NOT collapse,
allowing the user to click somewhere else.
This implementation will do nothing in this case.
So if I forgot that the Dropdown is open and click somwhere else
It seems stuck as I get no visual feedback what to do.
This may frustrate players upto a level where theey will kill the game.

In additon it does not collapse when pressing Escape,
instead the complete dialog is canceled.

Sorry Gun.

Good work otherwise. I will continue to review the usage and code.
