Triggered by #3341.
The bitcoin win32 build was relying on an old insecure version of libpng for no good reason. The libqrcode tools make use of libpng but we don't use the tools, just the library.
In turn, this libpng dependency pulled in zlib.
Remove both dependencies both from the documentation and descriptor.
Bump deps version to r10 (for good measure; the used parts of the dependencies don't actually change, so it may not be strictly needed).

Automatic sanity-testing: PASSED, see http://jenkins.bluematt.me/pull-tester/1be9e2f976bf0b4107024577585cc0c671255c6e for binaries and test log. This test script verifies pulls every time they are updated. It, however, dies sometimes and fails to test properly. If you are waiting on a test, please check timestamps to verify that the test.log is moving at http://jenkins.bluematt.me/pull-tester/current/ Contact BlueMatt on freenode if something looks broken.
