The --clean-packages and --clean-packages-all features were added just
a little too hastily, so overhaul them.
1. Don't do the test for whether or not the package is installed until
   we are sure both that it's up to date, and that we're not using -all.
   This makes the whole thing a little slower, but is more friendly to
   the "master build server" idea, and doesn't prompt unecessarily.
   Now more useful information is printed to help the user decide if the
   package can safely be deleted in the !-all case.
2. Try to display information for out of date versions more intelligently
3. Use a little more white space in the output to make it easier to parse

For both --clean-packages-all and --clean-distfiles-all use a simpler
method of handling the -all version.

Inappropriate prompting for --clean-packages-all was raised in:
