Alpha rewrite of Wordsearch Attack using Godot. — Word Attack Steam update #258961

There is now a "Play Godot version of WordsearchAttack" launch option that runs an early test version of the wordsearch game mechanics reimagined in the Godot game engine. It contains 2 test boards and 2 test word lists which are randomly selected when you start a new game. The QE/WASD keys rotate the board or WASD pan if Ctrl is held down, shift accelerates. Holding the right mouse button also rotates the board (x/y axis rotation in centre, z axis around edge), middle mouse to pan. Mouse wheel and F/C keys zoom in and out. Left mouse button selects letters. Space opens/closes the word list, holding right mouse button over the word list moves it, also holding Alt resizes it. Esc exits the game.
