Macros are mapped like so (for the group tab):
{1: {1: 73, 2: 45, 3: 523}, 2: {1: 32, ...}}

When a macro is deleted, these groups aren't updated. It'll be easy to update this to work when a user deletes a macro in SimpleMacro.

Solutions if a macro was deleted from the default editor

• hook into macro deletion?

Support for macro deletion within Simple Macro: aa8276a

Still need to support new macros and update (just remove + new)

I believe this is essentially done for SimpleMacro updates 88884b1

Still need to hook into the Blizzard API to handle updates outside of SimpleMacro
