ERROR: Remote 'bincrafters' already exists in remotes (use update to modify)

[hperrey]

A simple rm -rf ~/.conan fixes this -- maybe one could check for whether that directory exists in the script and advice the user? Just in case there is any leftovers from a previous install.

[mortenjc]

I am ok, with this, or we can improve the script in other ways.
Martin - your opinion on this?

For now, just do the manual install instead

[hperrey]

Alright, just realized that this also gets in the way should a previous install attempt have failed for whatever reason -- that is slightly more annoying than I thought then.
