Add render-full-map.md to community section

I made this tool https://github.com/VityaSchel/bluemap-full-render that allows you to export the whole map as a png image

I feel like this would belong more in the 3rd Party Addons list.
This just seems like the Readme of that addon copy-pasted.

Well that's not exactly addon as it's not integrated into BlueMap, it's a separate tool. I did copy readme of rendering part of map using python, but this tool allows to render the whole map

My apologies, I should have used its full name: "3rd Party Addons & Tools" list.
There are other tools that aren't directly addons on that list as well.
They then link to the addon/tool's own page, where it is explained how to use it.

In the case of the Screenshots from Python guide, there is no other addon to link to, as the guide is all there is.

I agree with Jelle that this probably fits better in the addon-browser :)
