Mike Gerwitz c33adee21d client: Truncate diff posted to server after first null
Before this change, since `undefined' is encoded as `null' when serialized,
there was no way for the server to disambiguate between unmodified values
and a truncation point.  For example:

  [ undefined, undefined, null, null, null ]

The above array represents two unmodified and three removed indexes.  But
this is serialzed into JSON as:

  [ null, null, null, null, null ]

It isn't possible for the server to determine what the truncation point is
from that diff.  The solution is to therefore truncate the array _before_
sending it to the server, providing a trailing null to indicate that a
truncation has occurred:

  [ null, null, null ]

The above means that the first two indexes are unmodified, and that index 2
and later should all be truncated.

* doc/client.texi (Saving to Server): New section.
* src/client/transport/XhttpQuoteTransport.js (_truncateDiff): New method to
  perform truncation.
  (getBucketDataJson): Use it.
* test/client/transport/XhttpQuoteTransportTest.js: New file with respective
  test case.
