Version 0.6.3

• Changed wording when no results were triggered to be less confusing by showing "~2" and/or "~3" when it isn't known that it won't work with py2 or py3. Before it would just show nothing in verbose mode for such files. (#19, thanks @hwine)
• Added results interpretation to usage info and README to better inform what "~2", "!2", and so on, means.
• Showing non-lax tip if no rules were triggered to try more thorough analysis.
• Corrected version-combining for bytesv3 (b'test') by not showing "~2, 3.0" but "!2, 3.0" since if bytesv3 was triggered it is on py3 and otherwise, on py2, type(b'test') = <type 'str'>.
