Fixes #460: Do not show variants by default in spack find.

This does two things:

1. By default `spack find` no longer shows variants.  You have to
   supply `-v` to get that

2. This improves the `colify` implementation so that it no longer pads
   the rightmost column.  This avoids the issue where if one spec was
   too long in the output, *all* specs would have space padding added
   to that width, and it would look like the output of `spack find`
   was double spaced.  This no longer happens -- the one bad line
   wraps around and the other lines are now single-spaced when you use
   `-v` with boost.
