[issue360] 'matches no packages' should appear for every argument

[Ed Avis at Labix Tracker]

New submission from Ed Avis <ed at membled.com>:

When you ask to install lots of packages in a single command, for example

smart install a b c

then if one of them doesn't match any packages, smart prints a message

error: 'a' matches no packages.  Suggestions:
   [...]

and then stops.  It prints this message only for the first argument that matches
no packages.

It would be better to continue and print the same message, if applicable, for
each other argument too.
