[Feature] Refresh configuration (like vim 'source' command)

Hello everyone,

I absolutely love zathura and use it everyday. It works great with my latex work flow, for reading college pdfs, and everything else.

I was wondering if zathura has any kind of command for refreshing the configuration file while it runs? Kinda like vim has :source. I change my themes programmatically, and it would be great to get zathura to change colors without a restart.
