New markers for i.m.table

At a certain point, while developing software for the i.m.table, we had to drop reacTIVision. Thus we were in need of our own markers for a required number of code combinations.
We had to make them as compact as possible although clearly recognizable in space. Vitaliy Slyusarenko came up with a binary code idea, which gave our markers a more "industrial" shape and 256 code combinations at first. So that is how our i.m.table markers look now.
