Beads can fall off abacus

As reported here: ​http://lists.laptop.org/pipermail/testing/2011-June/002226.html (not tested by me)

> Abacus 19 - broke it! managed to get the beads to fall off the bottom of

> This was weird enough that I retested it at home. Messed with all the
> settings in create your own abacus and broke it again. You have to move
> beads first then change the base or factor, eventually it breaks.

Thanks for filing the ticket. I overlooked this in Tabitha's testing report... Now I just need to figure out how to reproduce it :P

​http://git.sugarlabs.org/abacus/mainline/commit/d0e39b9a2976e6a579136e196f9cd1d6086a1d1d seems to take care of the problem. Please reopen ticket if it reoccurs.

Walter please note here if you have it in a new version, so Daniel can incorporate it in a new build if desired.

Just seen that Abacus 20 should be the one...
