Fix SSL domain indexing logic, whitelist using MAC instead of IP and make it persistent.

[buffermet]

Changelog:

• Fixed SSL domain indexing logic.
• Whitelisting clients is now done using MAC instead of IP.
• Whitelisting is now persistent.
• Some performance improvements.

To-Do:

The goal is to be able to list all HSTS preloaded domains, so for each domain prefix (www., a, b, c, ...) there should be another range of string mapped arrays. Ideally the indexing depth is automatically based on the size of the array.

Ideally the entire list of domains is only saved when the module is stopping.

A cookie tracker still needs to be implemented for spoofed domains.
