Update the docs

[Kovah]

• Fixes several spelling issues
• Fixes several code issues which led to a broken HTML page
• Updates some parts with new information
  • Adds information about CSS viewport units
  • Updates information about media queries for devices
• Removes some strong language from the docs

I used the grunt builddocs command to compile the .html files. I hope this is correct but it seems it worked flawlessly.

thanks!

Just FYI though. The Unity stuff (https://github.com/greggman/hft-unity3d) has become stand alone. Meaning it no longer requires anything from this repo and it no longer installs stuff into "happyfuntimes". It just runs on it's own. This has a bunch of benefits including that people can add happyfuntimes support into their apps and just ship them on steam/itch.io, etc..

I've thought about doing the same to this library using electron. The basic idea is to just make happyfuntimes a library you can use in electron. Then convert the samples and at first provide docs on how to generate shippable electron apps OR make an electron app that makes electron apps.

The benefits are the same. People can just ship their games. Users don't have to install happyfuntimes first. It also removes a ton of useless code.

unfortunately I haven't found the time. And, ... it seems like 99% of people making small experimental games use unity instead of html5. So, there hasn't been much pressure
