trurl 9802b684ae Rewrite WINGs/tree.c in Rust. 
This is a bit of a red herring, since WMTree is only used in wmmenugen, which I
don't think I've ever directly used. See notes at the top of tree.rs for more
musings on whether this should be in wutil-rs at all.

trurl 0a04a4c12e Remove depthFirst parameter from WMTreeWalk. 
WMTreeWalk is only called once, with depthFirst set to true, so we might as well
just hard-code that behavior.

Also, this parameter appears to have been misnamed (since the search is always DFS)
and should properly be named to indicate that it controls if this is a pre- or
post-order traversal.

trurl e1a263cc5b Prune unused WMTree API functions. 
This is a first step towards migrating WINGs/tree.c to Rust.

Happy finding: no parent pointer are actually needed, so we don't have to use a
shared structure for node pointers!
