    Issue #248: Python console doesn't support input()/raw_input().
    
    As noted by Massimo, we can just make the argument of raw_input() an
    optional argument.
    
    Also adding a modal implementation for input() so that it doesn't lock
    the Python console waiting from input from the plug-in stdin. As noted
    in Python doc, input() is equivalent to `eval(raw_input(prompt))`.
    Not all that safe, but in the end, it is the developer's responsibility.
    
    (cherry picked from commit 130ef5ce59a701344da79a224cc84495ab218df9)
    
    Note: it is untested on master since we don't have Python right now, but
    I don't see why it would not work here as well!
