Fix bug in punch timer

[rwols]

I played around with this (fun game!) and I noticed the color mod lerping not working as it should. Sometimes the texture becomes red at the very end of the timer. It's due to the logic in BillGates::Update. The m_punchTimer may become negative which causes the lerp function to wraparound. I am too lazy to fork this and submit a pull request on this Microsoft platform. Here is the patch to fix it:
