As requested in https://wildfiregames.com/forum/index.php?/topic/21935-resource-tooltips/
some mods might want to add descriptions for resources and display them in related places.
The attached patch adds support for adding resource descriptions, marking them as translatable and showing them in the top panel.
These strings in particular seem a bit useless, we can remove them and still add the code to support descriptions.
If someone has some proposals that wouldn't hurt.
The descriptions could also be shown in the summary screen code (which would need some rewiring), could be done in a simple ticket.
