Added Dicom support to SCIFIO

Converted the loci.formats DicomReader to SCIFIO components. See
ome.scifio.formats.DicomFormat. The loci.formats DicomReader has been
converted to a delegator and marked deprecated.

Necessary supporting classes were also migrated:
JPEG2000Codec
PackBitsCodec
JAIIIOService + Impl

These classes will not be converted to delegators until all SCIFIO
formats are converted (at which time they will move to loci-legacy).

As the JAIIIOService classes were moved to SCIFIO, the
MissingJAIIIOService test was also moved to SCIFIO, as the dependency of
scifio on scifio-devel would cause this test to always fail if it
remained.
Added setAxes method to ImageMetadata

Added a convenience method to ImageMetadata that sets both the axis
types and axis lengths in a single signature.

Motivated by the restructuring of axis types and axis lengths, as the
lengths can no longer be set independently of the types.
Refactored ICSFormat axis population

Instead of building arrays to populate the axes, they are now added
incrementally to make the logic clearer.
Updated scijava-common to 1.0.1

The scijava-common jar has been updated to the 1.0.1 snapshot.
Added SCIFIOApp

Added a scijava-common App implementation for SCIFIO. This plugin is
discovered by the AppService and provides version information, allowing
the scijava-common context to query and report the discovered SCIFIO
version.
Added domain specification to APNGFormat

The Reader in APNGFormat now defines the domain APNG images are commonly
associated with.
