modify list_packages() to preserve state, etc.

Browse Source 
This creates selection_state() (so that the user's selections can be
preserved when the menu is regenerated in the loop) and breaks out
mk_pkg_lists() (so that, when packages are removed, they are also
removed from the menu). Before, this simply broke out of the loop but
that forced the user to re-enter the menu if they wanted to do anything
else with it.
