Support for switching between official and semi-official color

[Supergamer1337]

Here with a MASSIVE update for hexit.

I was bored while waiting for something to run, and so I took the massive time investment of doing something I've been thinking about many times, adding support for the semi-official secondary color, #00BABE to hexit.

I know this is a large change, and may not be merged due to this. BUT, I do think it's a very cool change. Also makes some QOL changes to the user experience.

Thanks for your contribution! It is clear that this was both a true FEAT of effort and took an IMMENSE amount of time.

Your pull-request sparks this very important question: wouldn't putting an unofficial color on an official site make that color official? This outcome would be simply unacceptable. The point of hex.chalmers.it is to show the official COLOR (singular) of the IT division.

However, adding a notifier for when the hex code is copied is an EXCELLENT example of feedback, which is especially important in an application with such a COMPLEX, INTRICATE, and UNIQUE design as hex.chalmers.it. Good job!

It is difficult for me to alone determine whether this this should be merged or not. I've given my reasoning but someone else should definitely take a look as well.
