No-Pin Assignment for Macros 1-6

[arntsonl]

There's a bug in 0.7.8-RC1 with macros pin assignment.

I only check isValidPin() but I also need to check has_variable when looking for upgrades on macro1 through macro6.

I'm assigning this to myself.

Should be fixed in RC2. Will verify on full release and close.
