[Feature Request]: 'g' gets top item from stack

[awldune]

When getting an item from a floor stack, 'g' at the item select menu should pick up the top item from the stack. For example, 'ggg' would pick up two items on the floor rather than pressing 'g' and then having to choose 'a' twice. This keeps all of the keystrokes on the same hand when using roguelike commands.
