Custom PlantUML Server URLs (Settings page)

Hi Todd,

I’d like to ask that the hardcoded URLs on lines 74 and 81 in public/class-plantuml-renderer-public.php?) be customizable with strings set on a Settings page for your plugin. I’m assuming those two places are the only hardcode in the plugin, but you’d know of course.

Is it rude to ask what your donation/$$ would be for this change?
Thanks!

Steve
