Initial maven-ization.  Also added example keystore to use for signing jars.
Replaced use of TestNG in SAMTestUtil.
Generate sources and javadoc jars
Remove ranged versioned dependencies
Remove bcel and ant from maven dependencies
Clean up spacing; maven requests 2-space indents for POMs.
Add release profile, and move to maven-gpg-plugin instead of maven-jarsigner-plugin.
Adding oss-sonatype parent, XML version, and adding Nils Homer as Broad PoC for HTSJDK.
Adding dependency management section.
Added reasonable version ranges to mitigate potential version conflicts. When the build fails due to minor, generally backwards-compatible version increments, the better solution would be to figure out why it fails and to fix it (e.g. for snappy-java). Feel free to tighten or expand these ranges.
