Allow installation of specific versions of GRASS addons

[pmav99]

At the moment, g.extension only supports the installation of the latest revision of the svn repository. As a result, any non-backward compatible change in the GRASS-addons repo, means that existing code may break.

Being able to install specific versions of GRASS addons would mitigate a potential source of bugs and would make debugging of addon related code easier.

The 7.1 version of g.extension can ​theoretically install any online zip if it has the right Makefile. You can also download the right version and then install from the zip or directory. For example, here is installation for r57849 version of r.local.relief (URL can be retrieved from Trac):

g.extension r.local.relief url="https://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.local.relief?rev=57900&format=zip"

Could someone update documentation and close issue?

In 72792:

g.extension: example to download specific version from GRASS Addons (closes #2896)

[wenzeslaus]

An improved example from comment:2 is in the manual (see r72792). It will be online as a web page at one of these URLs:

• https://grass.osgeo.org/grass74/manuals/g.extension.html
• https://grass.osgeo.org/grass75/manuals/g.extension.html
• https://grass.osgeo.org/grass76/manuals/g.extension.html

If you with for this to be solved by parameters of the g.extension module, please create a new ticket (suggestions of interface, naming and use cases are welcome).
