Make libpamac as shared library to be used for both GTK3 and Qt versions
I'm an Archlinux user and I use Pamac as my main Pacman UI. I've made an AUR package for the Qt version but it seems there is no libpamac included in the build, so ATM I'm forced to have both versions installed. It would be nice to have a separated project for the library, so it could be possible to include it in an external package to share between versions.
