Macro Global Variable Watcher

Description
This macro displays the global variables within the FreeCAD system (e.g. FreeCAD.myVariable). The user may add and remove variables from the display, which may also be updated on a timed basis.

Installation
All the code for variableWatcher.FCMacro is in one macro. So installation is comprised of copying the code to the appropriate Macro directory and invoking the Global Variable Watcher from the Macro menu, the Python console or a toolbar button (the preferred method).
 * see How to install macros for information on how to install this macro code
 * see Customize Toolbars for information how to install as a button on a toolbar

Usage
Select global variables to be watched by using the rightmost pop-up menu. Click the "Display Now" button to immediately display the variable and its value, or click on the "Timer On" button to start an automatic timer. The interval for the timer is set in the far left pop-up menu. The topmost option on the rightmost pop-up menu is to update the list of global variables as they may have been created or deleted under program control.

A variable may be removed from the watch list by right-clicking over it or it's value, and selecting "remove variable".

Remarks
This is a pre-release version and not all aspects are finalized - especially the listing the global variable and their values.
