Added PyFormat.info to Text Processing section

[kaitouNeo]

What is this Python project?

It can make format() in Python more fexiable and convenient to use.

What's the difference between this Python project and similar ones?

• The syntax looks more human readable.
• The format specifier ( such as %s, %d ... ) can be omited, and will be repalced with {} .
• Padding and aligning strings.
• Support named placeholders, mean it can format the string with dict data structure as parameter of format().

Thanks for your contribution. I like .format() too, but it's a language feature instead of a Python package.
