Small Bugfix

Disabling the hint was slightly bugged.  For the very first match after a shuffle it would still hint if you waited a minute (edited)

I was using a basic flag guard before starting the hint timer.  I had missed that guard after a shuffle.  I decided that whole approach was needlessly complicated - instead I just set the hint timer to Godot's maximum 64 bit integer value.  Now, the hint isn't technically disabled you'll just have to wait 2.92271e+9 centuries to get a hint
