Simplifications around TypedValue
You can now specify Properties in QL

Implemented qlApply, and made it do the right things for Thing and
Property.

Simplified the PropValue stuff a bit, to reduce the overhead.  Couldn't
entirely eliminate the per-Collection boilerplate yet, though.

Added the ability to input Ints.
QL can now reference System properties.

This involved making anythingByName look up the app stack.  Is there any
reason for this not to work?  I suspect my original belief was that a
name was too intimate to the current Space, but I believe that less and
less.
