X.U.Scratchpad: Deprecate

This is i) broken and ii) just the functionality of X.U.NamedScratchpad
rewrapped (and not necessarily improved upon) at this point.

With recent changes to the way named scratchpads work[1], we would have
to export internals of X.U.NamedScratchpad in order to restore
X.U.Scratchpad to its full functionality.  This does not seem worth it,
as the latter does not bring anything substantially new to the table.
