Allow font changes

This is an awesome tool!

I think it could benefit greatly from having a font selector on the themes list page as well as the themes editor page. Reasons include:

• A particular font can affect how a theme looks, and vice versa
• Users looking to try out themes might feel differently about it when using their font of choice
• Theme creators will be able to see the effect of using different fonts with their themes
• This website could then also be used to test out different fonts!

@LightTreasure Thanks for the suggestion, this was something I had considered, although allowing custom fonts will be tricker to implement as we will need to add some infra for upload/host fonts. I wonder if the first step should be offering any Google Fonts (a limit set of only monospace, maybe??).

That is a good starting point! Another good starting point would be to support the popular Nerd Fonts!
