[GRASS5] Raster files suggestion: new directory layout

I strongly support the idea. Perhaps this could give us a chance to improve 
the data format as well? I think a limitation of rasters is that they are 
always 8 bitpp, whereas in many cases (black&white maps) it would be more 
appropriate to stick to 1bpp (far smaller files!).
But if this is complicated, of course it will be better to change the 
directory layout ASAP.
All the best.
