ref-manual: Added Smart-enabled package feed info to section.

There are steps the user can take to create a host-resident
package feed (repository) whose front-end is Smart.
The setup allows the user to install packages from the host
feed during runtime on the target.  The changes I made now
include that fact.

I also reformatted into a list some of the RPM limitations
and benefits as they now numbered such that I could list
them out as such.
