sumdb/internal/sumweb: simplify code, clarify comments

Followup work from CL 172964 review comments.
(That CL was in a different directory and is too hard to get back to.)

- Simplify to one cache for Conn.ReadTile.
- Replace Client.GetURL with Client.ReadRemote,
  which takes only a path, not a full URL.
  It works better for the client to take care of URL mapping.
- Rename FindKey to Lookup throughout (matches URL).
- Apply !-decoding in Handler.

exp

This subrepository holds experimental and deprecated (in the old directory) packages.

The idea for this subrepository originated as the pkg/exp directory of the main repository, but its presence there made it unavailable to users of the binary downloads of the Go installation. The subrepository has therefore been created to make it possible to go get these packages.

Warning: Packages here are experimental and unreliable. Some may one day be promoted to the main repository or other subrepository, or they may be modified arbitrarily or even disappear altogether.

In short, code in this subrepository is not subject to the Go 1 compatibility promise. (No subrepo is, but the promise is even more likely to be violated by go.exp than the others.)

Caveat emptor.
