Add tailwind CSS and live reloading

[webdev03]

This adds live reloading with electron-reloader for a better development experience so now working with Tailwind actually makes sense, because if you didn't have live reloading, you would have to kill the electron process again and again. It also works with the normal builds, as I wrapped it in a try catch block, because electron-reloader is a Dev Dependency. Tell me if you want it to be removed.
I haven't changed other styles to tailwind, though, tell me if I should.

You should also credit MystPi for helping with implementation!

I'd also like to add that instead of running npm run start run npm run dev if you want to work with Tailwind at the same time. When starting to develop and you aren't touching anything with Tailwind styling, please run npm run tailwind at least once.

Sorry, my editor messed up the formatting, that's why I wanted prettier in the old freecat, but since you say it broke Freecat, I didn't add it.

I have an opinion on that, but don't want to offend anyone, so won't say it.

Thank you so much for merging! Should I work on the other styles now?

Could you work on SpellCheckJS instead?
