zipfile tweaks for the 0.5.0 M1 release
Removing obsolete profile name from pom.xml

titan-dist's submodules were consolidated and the need for the
release-plugin-hack wart disappeared.

but apparently not
Fix titan-hbase mvn w/ -Paurelius-release

Maven's executing sign-artifacts before build-hbase-jar when
-Paurelius-release is true.  Tweaking it to be the other way around.

Disable javadoc plugin in titan-hadoop-1/2 modules
Disable log-tx by default
Sign cassandra testjar

Unsigned testjar prevents closing the release repo on Sonatype
Generate titan-hbase source and javadoc jars

Like the preceding commit, this is necessary to pass the automated
release acceptance tests on Sonatype.  The config is screwy because
titan-hbase is an assembly of titan-hbase-core, -094, -096, and -098
classfiles, and the javadoc and source plugins are not really setup
for that by default.
