Adding a note about MP instance
Refactoring to work with latest version of ConTeXt.

The way MP instances work has changed. Earlier, one could define a MP graphic
with any name

   \startuseMPgraphic{whatever}
    ...
   \stopuseMPgraphic

and simply use `\useMPgraphic{instance_name::whatver}` to call an instance.

Now, the MP graphic must be defined **with** the instance name:

   \startuseMPgraphic{instance_name::whatever}
    ...
   \stopuseMPgraphic
Changed the bounding box of mayanumbers

The previous bounding only covered the bars and not the dots. Now changing the
bounding box so that it the bounding box extends to the "invisible" bar if the
extra dots are greater than 3.

This gives a better visual appearance.
