[GRASS-dev] TclTk animator finished - replaces xganim

[Michael Barton]

Thanks for clarifying this. It isn't described anywhere in the xganim docs,
so I was unable to get it to animate more than a few maps.

The parsing in the new TclTk module is still simpler. It will correctly
recognize rast[1-100]. Also, no leading 0's are needed to make the series
animate in the proper order.
