Have the availabilty to add easiest in the queue "the best version" of a selected package

[chtof]

I suggest the following enhancement for himerge, the availability to do this :

- Select a category and a package (no need to select a version).

- Click on "+ queue"

Expected result : the "best version" of the package and the dependencies are added to the queue.

(Actual result : No package version selected).
