update to mobile + menu adjustments

nothing super exciting, just a small update for mobile things + the pop-up menu. i haven't tested these out too much yet, so i've uploaded them as separate files and kept the original versions intact, just in case i end up breaking something.

• the game header is now hidden automatically on mobile and passage height has been adjusted slightly, allowing for more text to display on screen at a time. clicking the top of the screen (it's actually just a hover bc i don't think touchscreen devices can tell the difference) will cause the header to show up.
• clicking anywhere in the general vicinity of the story passage should automatically close the pop-up menu without having to re-click on the header text.
• for those using this template in their existing games & just looking to update snippets of it, the changes are located in the <script> tags of the StoryInterface passage if you want to implement the changes for the pop-up menu, and in the section titled "stuff for the mobile header" in the Story Stylesheet if you want to implement the changes for mobile formatting.

as always, feel free to drop me an ask on tumblr if you run into any issues.
