Makes flagging easier
Moves REs, bonuses, etc below the game board to prevent misclicks.
You can also press 'x' to toggle the flag checkbox.
When flagging is on, hovering over a negg will reflect this.
The keys 'e', 'm', and 'h' will start a new game of easy, medium, and hard difficulty respectively.Persistent flagging means the page will remember whether you ticked "Flag" or not.
This is now a built-in feature of Neggsweeping.
