Sets the MetadataOptions to default

The MetadataOptions of the OMEMetadata are set to default by the
SCIFIOFormatWriter, which is all that can be done as in Bio-Formats it's
the reader that tracks MetadataOptions.
Updated Metadata population

The OMEXMLMetadataService Metadata population method now populates bits
per pixels, and now has a correct plane size calculation.
Implemented OMEAPNGTranslator

Can now translate from OMEMetadata to APNG Metadata.
ICSReader populates MetadataOptions

The ICSReader now populates Metadata options, which are significant to
the ICSFormat in SCIFIO.
Updated ICSFormat

The ICSFormat was significantly out of sync with it's Bio-Formats
equivalent, to the point of being non-functional.

It should now correctly mirror the legacy performance.
Implemented OMEICSTranslator

Can now translate from OMEMetadata to ICSFormat Metadata.
Math correction in writer plane size check

Was using bytes per pixel instead of RGBChannel count. Fixed.
Don't create unnecessary ImageMetadata

The OMEXMLMetadataService now checks to see if it needs to create
ImageMetadata instead of just always creating it, when populating
a Metadata object.

The previous behavior could lead to doubling up of Metadata, which would
then mismatch with the image/plane indices.
Fix RGBC check in OMEXMLService

The Metadata population in OMEXMLMetadataService was setting RGB to true
if the rgb Channel count was > 0. It should be if > 1, as 1 is the
default value.
Improved getBytes handling in BIPlane

Corrected the BufferedImage byte extraction, to differentiate 8 and 16
bit component sizes, as was done in Bio-Formats.
Always copy to provided byte array

In the SCIFIOBIFormatReader, when provided a byte array, as much as
possible of the opened array is copied to the provided array (instead of
only copying when the sizes matched).
Corrected APNG implementation

The SCIFIO implemenation was missing several features of the Bio-formats
implementation. This should be largely fixed now.
Corrected scifio-devel classpath

Added log4j jars, removed netcdf.
