Flashing upon page switch

[ggtylerr]

Whenever a new page is loaded on the site (not including the first page loaded), the colors are not loaded properly, until a few seconds later. This is possibly due to astro-spa.

Fixes attempted:

• Disabling defaultAnimation (Helps, but the colors still don't load)
• Moving the theme loading script to the start of body
• Setting the background colors in the script itself, in case the stylesheet didn't load
• Setting a "preload" class to body that disables transitions, and then removing it a second later.

It's possible that a fade-in animation that just sets the BG color to the theme's color would fix it - I'll try implementing this tomorrow (I've already had to deal with an aneurysm trying to fix this over the past 1-2 hours.)

Astro-SPA was removed recently following a recent package update and patch for #4, and the issue seems to be gone now. For Chromium users. On FF, the issue is still present. No idea why.

Partially patched by making the default theme dark instead of light, though flashing is still present. Most likely just gonna rewrite the theme switcher script.
