Consider adding DesignPatterns repository

[drt-pl]

Currently listed repository has only 4 design patterns (with very generic examples):
https://github.com/sftrabbit/CppPatterns-Patterns

I would like to recommend adding following repository:
https://github.com/drt-pl/DesignPatterns
Written in plain C++11.
All original 23 patterns plus two extra (Null Object & Object Pool).
Probably best examples on the internets.

Thanks!
