Bingo Master Board for Web Commits 2018-09-15 and 2018-09-15-1

Got you guys two commits today, which I will combine into a single blog post.

Commit 2018-09-15

• The How to Use page is ready to go. It's organized into sections so it's easier to follow through. For instance, you'll find the keyboard shortcuts in Tips & Tricks.

  Have a good look at it; this is the longest time I've spent working on instructions.

Commit 2018-09-15-1

This commit focuses on optimizations, especially for iOS devices.

• Fonts and images now preload, which should reduce jumpiness throughout the UI.
• On iOS devices, double-tapping will no longer inadvertently zoom in the page. You can still pinch to zoom if you so desire.
• On iOS devices, the page is now fixed so you won't inadvertently scroll the board up and down.
• Fixes font size issues for some iOS devices
