Make macros non-static

[alphappy]

Currently, macros are static; if macro A executes itself (once, not endlessly), it resets its own state.
For example, the following macro only runs R~20 once, regardless of where Slugcat starts.
If non static, it would run R~20 once for every L~20.

/NAME: foo
L~20
>goto 1 if scug located left of 500
>execute foo
>label 1
R~20
