Iup and nukclear interface in D.

[mogu via Digitalmars-d-announce]

http://code.dlang.org/packages/iupd
http://code.dlang.org/packages/nukleard

iupd removes all deprecated items in IUP, current version is IUP 
3.18.
nukleard may have some bugs in name mangling. Does a struct's 
field name like `null`,
i changed it to null_, may be issue? Can pragma(mangle, "name") 
help in this context?
