-pkg/server/share.go handles share(d) blobs.
-pkg/blobserver/gethandler no longer deals with share blobs
and has been rewritten like the other handlers (no more auth
in there).
-client and signhandler changed accordingly.
-serverconfig: auth moved up in makeCamliHandler
-share parameter added to the user level and low level config.
-share URL is now http(s)://host[:port]/[prefix/]share/sha1-xxxx.

This allows to set a signature time (instead of using time.Now()),
so that identical files will result in identical permanodes.

no special credentials/auth yet.
pkg/blobserver/handlers/get.go moved to
pkg/blobserver/gethandler/get.go to avoid
a dependency loop with the json sign helper.
pkg/server/sig.go was moved to pkg/jsonsign/signhandler
because it seemed inapproriate to import in
pkg/blobserver/handlers/upload.go something from
pkg/server
