Wrangle/UnWrangle name swap

We realized that when we changed the name of the Tranform/RotateTransform
Node methods, we accidentally gave them names that are the reverse of normal
Oblong usage.  In Oblong, a 'wrangled' value is typically one that has been
translated/rotated etc FROM absolute space, INTO some object's particular
coordinate frame.

We felt that we need to rectify this quickly or risk a lifetime of
confusion.  So we are fixing it here.  Sorry!
fixed the sample makefiles to have a make clean target and correct spelling
