Add the ability to enable full logging for LoadLogs.

This works by clicking a button in about:net-internals to turn on active logging.

Right now full logging means:
  - Instead of just the most recent 25 requests, keep all requests info.
  - Instead of limiting each request to 50 log entries, keep all log entries.
  - Instead of saving the first 1000 bytes of request URLs, save all its bytes.

In the future full logging will be expanded to include other log events, and also string messages (so it can mirror what was sent to LOG(INFO) / LOG(WARNING)).
