More HTML style options, browser history, and work on the Readme.md

‎
Ok, so over the last 6 hours this is what I worked on. First, I worked on adding more style options, so now you can set font size (another way) and set font boldness (like normal HTML), and you can now add custom number values to the vertical alignment (that in the vid is shown on the homepage!).
‎
I also worked on the browser history now, saving it to a txt file. You can scroll back through what you’ve searched before (and add a button to clear it next update).I also was working on the readme, making it clear and better before the ship.
‎
Overall a good day, and I think I’ll try to do the settings menu, aswell as support for buttons in the viewer (though they probably won’t do anything thanks to not having JavaScript), so yeah!
