[FEATURE] Add view/fetch description for optional dependencies for aur and alpm packages if it possible

As Optional deps can be extensive, I have to look how I would want to implement this.

At the moment Optional deps can be viewed and installed from the preflight window in the Sandbox Tab.

Check it out if this works for you, or if you want to have it shown for example in the "Package Info" Pane.

OK, I'll take a look, but it might be better to show it in the package info box.

Thats the question. Do you need to know a optional depends when you are looking through packages?

Or do you only need to know them if you want to install a package?

For me it is the latter, what do you say?
