values loaded as NumericTextFrame even when not numeric

  File "media/metadata.py", line 2, in u
    return + tagvalue
  File "lib/mutagen/id3.py", line 11, in __pos__
    return int(self.text[0])
ValueError: 'invalid literal for int() with base 10: 'www.example.com''

class NumericTextFrame(TextFrame):
    """Numerical text strings.

    The numeric value of these frames can be gotten with unary plus, e.g.
        frame = TLEN('12345')
        length = +frame
    """

Perhaps my thinking is backwards, but I think the value of the data should 
inform the type.  There is no end of junk in MP3 files.  Mutagen should make 
fewer assumptions that a type that is what the spec says it should be.
