Added some improvements to counting buttons for the next Typica release.

Previously you needed to reset the count between batches and if you were doing several product development progressive roast batches and wanted the annotations to change between batches you had to set those manually.

Now you can set your annotation to something like %A-%1 and the %1 will, as usual, increment every time you press the button (but auto-reset at the end of the batch) and %A will increment between batches A, B
