doc: continue renaming location to project in documentation

[petrasovaa]

Some cases are simply replaced (location to project), in some cases 'coordinate reference system' or 'dataset' are better replacements.

I reached r.in.lidar, will continue tomorrow. As commented in the other PRs, I was also trying to fix places where both project and projection appeared together in the same sentence or message. I believe, where possible, CRS is a good replacement for projection.

I went through all files changed now. Some error messages I left untouched as they should be modified in r.in.gdal, v.in.ogr, r.proj and v.proj, IIRC. For a different PR perhaps :)
