dropunused behavior change: Now refuses to drop the last copy of a file, unless you use the --force.

Browse source 
This was the last place in git-annex that could remove data referred to by
the git history, without being forced.

Like drop, dropunused checks remotes, and honors the global annex.numcopies
setting. (However, .gitattributes settings cannot apply to unused files.)
