#46 gin-cli as conda package

With git-annex being available as conda package it would be very nice to be able to also use the gin-cli also with conda.

As a temporary workaround I am currently manually adding the gin-cli to conda environments. A short summary of this procedure can be found here: https://gist.github.com/JuliaSprenger/ef009154d61716d85710772672749fbf

Sorry if this issue is a duplicate. I vaguely remember a similar discussion earlier, but can currently not find it any more.

The corresponding gin-cli github issue can be found at https://github.com/G-Node/gin-cli/issues/208.

I will add the workaround comment over there as well.
