* Mangle stupid defaults test so that it compares tables, and not a non-deterministic string representation of one.
It's still extremely dumb and annoying to update. (i.e., feel free to kill it with fire in a subsequent PR, I think everybody would cheer).
* Rewrite DepGraph to be deterministic
i.e., fully array based, no more hashes, which means no more pairs randomly re-ordering stuff.
Insertion order is now preserved.
Pretty sure a couple of bugs have been fixed and/or added along the way
;p.
* Resync frontend/apps/filemanager/lib/md.lua w/ upstream
And use orderedPairs in the attribute parsing code, just to make that stupid test happy.
