Remove knowledge from the library to install packages.

Browse source 
The library is only responsible now to find all binary packages
from repositories, sort them and create a dictionary with all
details. The frontend (xbps-bin) provides support for this,
and this allows for more flexibility and removes some stuff
that didn't belong in the library.

While here implemented support to show total download/installed
size for all packages that are going to be installed.

Next step will be to implement user interactivity before
installing/removing/updating packages.
