pactree: add -s option to walk sync DBs
Add a whole lot of bloat to parse pacman.conf and only a few lines to use the list of sync DBs instead of the local DB. Dan: I fully plan on this being temporary and us finding a better way in the future to parse pacman.conf from multiple binaries. Adding a standalone config parser is probably not the right way of going about things, but for now it is by far the easiest.
