implemented _set()

made _craft_set() redundant, removed end as hot key.

If you dont have a value in the qty box when using _set() will throw
error. I am pretty happy with how it turned out.
small change with function _set()
change bind key to x

added the following bindings, harvest(cutgrass), forage, botanize and
pick sprout.

press button on GUI then press home to bind. this will open a console to
bind that command to x
change bind() check to see if already bound
