Multiple packages installation should happen together about pacback

[JustinTimperio]

While I understand the frustration this is really not how pacback was meant to be used. Rolling back a long list of individual packages isn't something you should be doing constantly and defeats the automated nature of pacback. With the hook installed it's pretty much set and forget.

I'll take a look at this though because I think it is important to avoid any version conflicts that may happen in between individual up/downgrades.

I see. I was also imaging a "no strings attached" mode, if I can explain.

Still, it seems to me like installing-everything-at-once would be useful either way.

This is now changed.
