This makes the REPL pick up on the words 'needs' and 'loads' when they sit at the top level. If they are followed by a string literal and a double semicolon token, the REPL loads a file (like previously with #load and #need). The motivation behind this change is to make sure Candle accepts HOL Light source files with as minor changes as possible.
