Make short links two characters shorter

By breaking up the $_GET array and grabbing the key (what used to be l),
ignoring the value, we can shorten links by two more characters.
This is kinda hacky since it does this for multiple get values
-- Still need to test to see what happens with multiple link ids.
I assume it will just go with the first id given
