Support whitelisting passwords and domains

[asaada83]

We often use weak passwords for internal/non critical test apps. It will be great if I can whitelist specific passwords or domains that the plugin won't alert me every time.

+1 on this - I would love to roll this out enterprise-wide but that's a non-starter without ability to whitelist domains. The extension would just pop all the time for our QA team's test accounts and similar things which are likely to have common / easy passwords, be design.
