Stratum ore: Allow use with no noise for simple horizontal strata

Browse source 
If either of the 2 noise parameters are omitted the ore will occur from y_min
to y_max in a simple horizontal stratum. As this does not compute noise
performance improves, and is ideal for placing many layers.

Clean up some nearby ore documentation.
