[freenet-dev] Patch: Report CHKs of single blocks in SimpleProgress

[Jano]

Hello,

the attached patch adds an URI field to SimpleProgress messages which reports
the CHK of the just inserted block. Does nothing for fetch requests.

This is potentially useful for filesharing programs, which could communicate
these blocks to downloaders allowing them to prefetch these blocks before the
insertion has completed.

This should encourage filesharing devs to reuse the insertion framework of the
node, instead of developing ad-hoc solutions (like freemulet does).

Here follows a sample client/node messages with the patch applied (against
r19348)
