RegisterControls Update
From Jeremie Leroy - XOJO Controls Wiki
The RegisterControls module is used by all custom controls to handle the registration code.
Xojo 2014r3 introduced some new features that now need a stricter definition of Constant values. Therefore, it is necessary to update the RegisterControls Module when using Xojo 2014r3.
