New libs
fix missing plugin .jar in scifio and knip.io

due to the build script, these jars were deleted, even if we still need
them. build script has to be adapted.
New libs

From now on libraries in "Bundle-ClassPath" entry of the MANIFEST.MF are
listed alphabetically with the exception of the first .jar (main build
artifact) always being kept first.

Also fixed build.properties in which library versions had fallen behind.
ScifioImgSource: Fix bug in close of underlying image source

closeNow() called close() of the wrapped reader, which in turn called
close(false) on the wrapper itself, which did nothing. calling close(false)
directly solves this problem.
