Fixes a minor bug on Firefox on Android. That's all.

Fixed an issue where people with timeouts of 0 couldn't change their settings. Now, they're adjustable but that day's timer is still used up.

Introduces the major new delay pages feature: Turn it on and set a time, and all tabs going to a blacklisted page will be delayed for that amount of time before allowing access to said page, and then starting the actual timer.
Also cleans up code to more efficient and correct versions of methods and processes, and allows 0 minutes on the timeout, effectively always blocking blacklisted sites.

New version released! With whitelists and the two abilities to a) lower timeout time even with no time left on hourglass and b) have changes in timeout time take effect immediately. Also fixed a super major bug that didn't let hourglasses expire.
Why didn't anyone tell me about this :<

Fixed a major bug where changing the blocking time would not affect the hourglass timer the next day.
