New Red theme added

I've added a red theme for the timer.

Hi, the added changes look good... But, it looks like you also reformatted most of the code, probably through some kind of reformatter that your IDE has. This makes it difficult to see the actual changes.
A pull request should typically have a concise theme or goal. This one should only do what's needed to add a new theme to the timer.
How the code is formatted is typically up to the person or organization that runs the repo, and more advanced projects may have a style guide for reference. Regardless of which is more readable/better, a major overhaul to reformatting like this should be its own pull request, not put together with a style addition.

Here's what I recommend:

1. Copy and paste the relevant changes in the html/js into a text file (notepad, etc.)
2. Revert this commit
3. Paste the relevant changes back
4. Make a new commit(s) with only the relevant changes
