With the Duplicate button a macro is duplicated with a new name, e.g. duplicate a macro named "MyMacro.FCMacro" and you get a new duplicate file named "MyMacro@001.FCMacro", but the user has opportunity to override the new name with a name of his own or to cancel the operation.
Functionality is similar to already existing ability to create copies of the .FCStd file, only for macros, and this must be done manually for each new file. Will be useful to coders mostly. Expected use case could be to save a history of the macro periodically as changes are made or perhaps to duplicate the macro first, and then make changes to the duplicate, eventually replacing the original once satisfied with the changes.
New code is based largely on existing code from rename operation, but with QFile.copy() instead of QFile.rename() used, along with other changes needed, such as generating the new suggested filenames.

Not sure how to make the Duplicate button label text translate when changing languages.
This adds the ability to enter things like 6 * 25.4 into the distance line edit widget during scaling operations in the image workbench. Can also enter something like math.pi * 3 or 2**3, etc. Basically, any legal python input can be used.
Using eval() is not considered a secure way of doing things, but in this context the user would be entering malicious code into his own computer. Also, what can the user do in eval() that he can't already do just by entering directly into the python console?
Adds a button labeled Addons... to the macros dialog below the create, edit, delete, and rename buttons. Clicking the Addons... button will open the same dialog available from Tools -> Addon Manager menu.
Convenience for experienced users, but new users who might not know about the addon manager will be able to see it here, too.
