Changed the look of bazaars.

Here, walls will always be golden (yellow) and the floor will be any of blue, red, lightgreen, lightblue, magenta or green, depending on the dungeon depth (modulo 6). This might be a bit weird, but guarantees the same colour regardless how often the map is redrawn. Also, bazaars should be sufficiently rare for that not to matter.

Removed all SHUFFLE statements in bazaar.des about wall type - it's all rock now.
