iMacro

This is an update to the default Blizzard Macro window which adds new function.

- dynamic search for icons when creating or modifying macros
- "Broadcast" button to print a macro line-by-line to the specified chat target
- right-click context menu for macros (copy, delete, move, rename)
- copy-to/from Character Specific tab

This work was originally done by Draznyth. I will continue to maintain the project as long as their is a following for it and I have time. I wanted to issue a thanks to the original author for his hard work on, what I thought, was an exceptional idea.
