[Trunk] Reading OXZ from nested OXP directory

[Keeper]

On the PC version at least, I noticed that 1.79 will read an OXZ file that is not directly in the "AddOns" folder, but rather nested inside an OXP folder, e.g.:
Oolite/AddOns/MrFlibble.oxp/IsVeryCross.oxz

Should it be doing that?

Until we get around to a better way of letting players organise their AddOns folder into subfolders, yes.

I’m gonna go with “no”.

Supporting subfolders should just be a matter of moving the [dirEnum skipDescendents]; at ResourceManager.m:251 up into the if case. (I still maintain that not calling it in the if case has always been a bug.) To avoid amusing shenanigans it would be best to filter out symlinks, though.
