Use Macros.row/.col instead of macroAction params

To make the signature of `macroAction` simple, the `row` and `col` properties
are not passed in every time anymore, but they are available as `Macros.row` and
`Macros.col`, respectively.

This keeps the function simple, but still allows access to these properties for
the rarer case of needing them.
