Keyboard shortcuts: Handle MetroUI naming non-standards of some keys in Macros

[sharmstr]

Macro keyboard shortcuts dont take into consideration MetroUI naming conventions. For example, Control will correctly change arrowright to right when saving the macro. But when you press right, it doesnt do the conversion from arrowright to right. You'll get the "Macro not found for arrowright" error.

Obviously not a big deal since I'm probably the only one to come across this. :)
