Priority should appear on directories if descendants have the same one

[Udasomu_Shakerabu]

I regularly download torrents with subdirectories, and set various priorities to them, on a subdirectory basis.

While we can set a global priority to a subdirectory without having to open it, we cannot see the priority of its descendants without expanding it (we can use the "Expand all" option in the right-click menu, but for torrents with a lot of subdirectories, it could take more time to check all entries...).

I suggest that directories show a priority entry in the priority column of the file tab, if all their descendants have the same priority set.

The best, for consistency, would be to show a "Mixed priorities" entry for directories, in case of mixed priorities set for their descendants. I don't know what the icon for it should look like, though. It should be well-differentiated from the other ones, so we can quickly differentiate them in long lists when fast-scrolling.

I found bug #2156 which already talks about showing a "do not download" status on directories for which all files are set to "do not download". So my feature request is a generalization of that.
