Reorder kryo.register statements in ADAMKryoRegistrator

[heuermh]

I'd like to clean up ADAMKyroRegistrator by removing package imports, using fully qualified class names, and sorting alphabetically, with blank lines between packages. E.g.

// package org.bdgenomics.adam.models
kryo.register(classOf[org.bdgenomics.adam.models.Coverage], new AvroSerializer[org.bdgenomics.adam.models.Coverage])
kryo.register(classOf[org.bdgenomics.adam.models.ReferenceRegion], new AvroSerializer[org.bdgenomics.adam.models.ReferenceRegion])

// package org.bdgenomics.formats.avro
kryo.register(classOf[org.bdgenomics.formats.avro.AlignmentRecord], new AvroSerializer[org.bdgenomics.formats.avro.AlignmentRecord])
kryo.register(classOf[org.bdgenomics.formats.avro.Contig], new AvroSerializer[org.bdgenomics.formats.avro.Contig])

// package scala
kryo.register(classOf[scala.Array[org.bdgenomics.adam.models.Coverage]])
kryo.register(classOf[scala.Array[org.bdgenomics.adam.models.ReferenceRegion]])
kryo.register(classOf[scala.Array[org.bdgenomics.formats.avro.AlignmentRecord]])
kryo.register(classOf[scala.Array[org.bdgenomics.formats.avro.Contig]])

The way it is now is confusing and has resulted in missing and duplicated register statements.

Seriously. This drives me batty as well.
