Use undocumented API call to get cached Windows passwords

This code explains how to call WNetEnumCachePasswords to get windows cached passwords: DUN, NetBios, Internet folders, etc. This function is undocumented, but it is based on a program by Vitas Ramanchuskas. I just transalted it to Object Pascal and commented almost every line. Enjoy, and make a good use of it. And vote for me if you like it :D
