Pkg2 package version preference

[Keno]

I'm noticing that when requiring BinDeps with both v0.2.0 and v0.2.1 available, Pkg2 chooses v0.2.0. While this is of course not wrong, I was wondering where this was intended.

This is indeed a bug. I can't push a fix ATM, but the fix is trivial: change true to false at line 36 of base/pkg2/resolve/versionweight.jl. Sorry!
