added pot2wl.py utils

[hashrepublic]

Added an utility to convert potfile into wordlist.

The utility can do :

• Convert potfile to wordlist (dumbly get the last part after the last :)
• Convert $HEX notation into human readable (--unhex)
• Sort by occurrences, usefull when concating multiple potfile in order to create a master wordlist (--sort)

Hope it will be useful.

Python is too slow. I have a C version that is much faster, I will add it sooner or later ;)
