Tooltips, performace, more presets!

Just dropping in to showcase the recent improvements I’ve made to Cellarium!

• Added tooltips which describe the purpose of all buttons and sliders
• Added several new presets
• Ported everything to WebGL2, making many improvements to performance. Most machines should be able to handle 4096x4096 simulations at 2x speed!
