Credential Storage via SQLite

[ustayready]

Credential storage should be moved from the .cache and .sniped files into SQLite using standard tables. This will make it much easier to run multiple phishing campaigns using different modules while making it a much cleaner approach. It also eliminates the potential for race conditions, locked files and all kinds of other problems.

I'm a big fan of http://dataset.readthedocs.io/en/latest/ - should make this way easier.
