Clarify usage of layouts

[mlennert]

Currently, there are different files in the layout directory. Some seem to be used, others not and when one looks at the files in the content directory one can find a very diverse usage of these layouts, probably stemming from massive copy-pasting for creating new pages (at least that's the case for me):

`grass-website/content$ grep --exclude-dir=news/ -R "layout:"

download/mac.en.md:layout: "os"
download/docker.en.md:layout: "os"
download/linux.en.md:layout: "os"
download/data.en.md:layout: "data"
download/addons.en.md:layout: "os"
download/windows.en.md:layout: "os"
about/history.md:layout: "general"
about/elements.md:layout: elements
about/brand.md:layout: "brand"
about/license.md:layout: "overview"
about/community.md:layout: "community"
about/history/van-warren-notes.md:layout: "general"
about/history/releases.md:layout: "general"
about/history/web-evolution.md:layout: "general"
about/history/gnu-release.md:layout: "general"
about/credits.md:layout: "credits"
contribute/development.md:layout: "devel"
contribute/donations.md:layout: "general"
contribute/community.md:layout: "contribute"
contribute/sponsors.md:layout: "contribute"
learn/books.md:layout: "overview"
learn/overview.md:layout: "overview"
learn/manuals.md:layout: "manuals"
learn/tutorials.md:layout: "overview"`

I would need some guidance on this:

1. When do we need a specific layout file ?
2. If no specific layout is needed, which would be the main layout template ("general" ?)

I can answer for what I understood, but could be wrong

I would need some guidance on this:

1. When do we need a specific layout file ?

if the layout is different from a general one (for example different number of column or images in some specific place, ecc), however each content file need a layout file

2. If no specific layout is needed, which would be the main layout template ("general" ?)

this could be (at least a general template for each section "download", "learn", "about"..), but right now the website is developed in different way

This is the most clear example of why we need #57, i.e., a website contributor manual and documentation about the website structure

@mlennert is it more clear?

@lucadelu, as @veroandreo said, this is actually a call for a clear manual. The situation seems to be a bit less based on arbitrary copy-pasting of existing files now than before. But there still is no clear rule detectable for me. Ex: why do most pages in learn/ use "overview". If there is a general template for the learn section, shouldn't this better be called "learn" ?
This is probably not very fundamental, just a question of documenting clearly what future contributors should adhere to.
