Add the option to use blizzards pull timers

[michiruf]

Describe the problem

Hi there, I downloaded BigWigs a few days ago, and I really like it. You actually can configure it the way you want.
But one thing I am really missing: the ability to still use the pull timers blizzard provides.

I personally try to keep my game as close to vanilla, where it is possible without losing functionality. IMO this is one of these cases. I guess that this theoretically should not be too hard to achieve, but I havent looked into LUA yet.

What version of BigWigs are you using? (Stating 'latest' is not useful)

BigWigs 353 (032cac4)

Thanks
