fixed a few float/integer issues in stackwriter
Slot/Operator: If an exception is raised during connect(), setValue(), or _setupOutputs(), revert back to the disconnected state.
OpStreamingHdf5Reader shouldn't close the file every time setupOutputs is called.  It's up to the user to close the file at the right time.
OpWrapSlot: Added an empty setInSlot() implementation.
implement setInSlot for OpWrapSlot

minor corrections and improvements to opInterpMissingData
Npy and Hdf5 readers: Don't require all 5 axis keys in the default axisorder slot.
slot: If an exception is caught during disconnect() while we're already handling an exception, print the second exception but continue raising the first one.
Operator: Added support for the special NOTREADY metadict attribute, which can be used by an operator during setupOutputs to specify that a specific slot is not actually ready, despite the fact that setupOutputs completed without any errors.
OpSingleChannelSelector: In setupOutputs, Output.meta.NOTREADY if there aren't enough input channels to provide output yet.
schematic: Color-code slots according to their ready status
OpVigraWatershedViewer: Added a fixme.
Op5ifyer: Copy all metadata from the input.  Also, add 'original_axistags' and 'original_shape' metadata attributes.
IO Operators: Don't accept a default axis order (users must use an Op5ifyer), and don't automatically insert a channel axis to the output shape.
Copied testOp5ifyer from volumina repo.
