Updated the documentation for the "property" command to include the 

new "plane" property type (which apparently was not previously
documented when implemented, an oversight), and also (added by
request) to add a reminder that the "MASKHINTS" property only works
in conjunction with corresponding "mask-hints" records in the tech
file.

<I>NOTE</I>: A mask hint will only appear in the GDS or CIF output
if there is a corresponding "<B>mask-hints</B> <I>type</B>" record in
the tech file's <B>cifoutput</B> section as part of a <B>layer</B> or
<B>templayer</B> which determines when and how the mask hint is handled.
Usually the mask hint is OR'd with the rest of the layer, but that may
