Mobile Formatting

It's been a while since I did one of these updates, but at long last, the update to mobile formatting is done. It's very simple: on the mobile version of Ace Linguist, the font will be bigger and there will be more space between the lines. Previously, the font on the Ace Linguist mobile version was terribly cramped - it was basically the desktop version of the site scaled down. This change should make it easier for mobile readers!
