Macro Toggle Drawstyle

Description
When working with FreeCAD there are times when you want to quickly change the Drawstyle of the object you are working with. This is available through the Drawstyle pull-down menu where any Drawstyle may be selected. This macro makes 2 of the Drawstyles available as a clickable button on a toolbar which the user may click to toggle back and forth between the two Drawstyles. The user can modify the macro code to select which 2 Drawstyles they wish to toggle between. This does not add functionality missing in the Drawstyles pull-down menu, but rather an increased convenience level.

Installation
Installation is comprised of copying the two code to the appropriate Macro directory and invoking it from the Macro menu. It is much preferable to add it both to a toolbar so as to be more easily available.

User Interface
The selected object will be redrawn in the other drawstyle specified in the macro.
