GETxxx hooks

[stig.madsen]

May be a minor issue and nothing more than wishful thinking but it would be nice if hooks were to be implemented with the GETxxx AutoLISP functions (or Utility object equivalent functions), - meaning the possibility of calling a function that could track dragging, verify input (more effectively than INITGET) and so on.

E.g. (getdist pt "Enter distance: " 'doTracking)
