Adds the sidebar
Rearranges, adds border-box

Prepares display to show every time site is accessed

Adds procedure and keypress, 't', for unit testing

- Adds keyevents to get the 't' key - in order to test pointer
lock, user had to engage, which means you can't type the test
command into the console while... your mouse is locked...
- Adds lines in index html and js to access testing
- Also adds some error handling for pointerlockerror, though
it seems to me that all errors other than a user gesture error
will be taken care of beforehand.
