Remove jQuery from home page

[mrwweb]

I'm currently seeing 3 console errors on the homepage (index.php) in Firefox and Chrome. It appears that this is because Googles JS loader used to load jQuery 1.3.2 (😱) is deprecated.

I believe the only purpose for jQuery on the home page in the first place was the password "chromahash" function. Given that this hasn't been working for quite some time (I think), I'd propose we completely strip jQuery off the home page and drop the chromahash function.

Any objections? Happy to submit the PR.

Sounds good to me!

Sounds good. I'll get that done sometime soonish.
