Bug fixes

• When submitting bugfixes please show a before and after screenshot of the fix, and a description of what the fix does.

Description:

Replacing "https://gilbn.github.io/" with "https://themepark-dev.github.io/" in Javascript files as former doesn't work anymore, and the replacement domain is still hosted on GitHub.

Benefits of this PR and context:

The video background won't work with the broken URL.

How Has This Been Tested?

• Tested in self hosted environment.

• Unraid 7.0.1

Source / References:

• Was discussed on Discord quite some time ago, and was encouraged to submit PR with fix.
• Have submitted several PR's, closed all previous ones, as this one is most thorough as I've patched all four effected Javascript files.

Hi. Thanks for the PR. Can you update it to be https:\/\/theme-park.dev\/css\/addons\/ etc

Hi @GilbN, I'm a bit of a novice with source code repositories, and I made a bit of a mess when trying to get the changes uploaded the way I want, but hopefully it is all now showing the way you prefer, including the update of the video URL's to your preferred domain.
