Pre-release fixup

  * Updated descriptions to be a little more descriptive.

  * Updated store_loot calls to inform the user where the
loot is stored.

  * Removed newlines in print_* statments -- these will screw
up Scanner output when dealing with multiple hosts.

Of the fixed newlines, I haven't see any output, so I'm not sure what
the actual message is going to look like -- I expect it's a whole bunch
of newlines in there so it'll be kinda ugly as is (not a blocker for
this but should clean up eventually)
