Use same fonts as Lemmy UI, search form update

[Mister-Digital]

The last update removed font declarations in the stylesheet. I'm adding the same font family back that the Lemmy UI is using as well. I've also wrapped the search input into a form to have default features like search on enter, prevent empty submits, etc.

Can you target your changes to the develop branch instead? So that I can bundle this into the next release instead of creating a new release just for this?

Thanks. Let me test this tonight after I get off work from my day job and if everything is working I'll merge this.

Thanks for the help.
