removed all defines of geoms, implemented setgeoms() instead, added config.anselm.h to show how I'd like to see that people edit their geoms

added bx, by, bw, wx, wy, ww, wh, mx, my, mw, mh, mox, moy, mow, moh, tx, ty, tw, th, wx, wy, ww, wh ad variables

implemented setlayout in the way proposed on the ml, split tile() into two functions, a third will follow soon

made the basics of the tagging concept working -- if people want dynamic tags, that's even possible with this concept, the vtags[] array needs to be modified during runtime for this -- the new code is quite experimental, ugly and needs polishing
