Make a release script and some fixes for Sonatype in build.sbt

BTW, I faced an issue that Scala version suffixes are missing. I think I always followed the current procedures so far if I am not mistaken so I suspect it's an issue somewhere.

For 0.5.0 release, I had to make some minor fixes in build.sbt.

I'm going to fix the script when next release is to be done later if I need to fix something else.

This makes sense. Yes, I was afraid that the several changes I made to the build script might have caused an issue at release time. I think the issue here is crossPaths. When false, it seems like the Java test suite is not run. Changing it to true looked like the recommended fix, but the flag really is about building separate outputs for different Scala versions. https://www.scala-sbt.org/1.0/docs/Basic-Def-Examples.html

If the issue is only that there is target/scala instead of target/scala-2.11 then maybe the answer is to build separately for 2.11 and 2.12 or something.

Or you can just set this to false if it corrects the problem and we'll later find a different way to run the Java suite.

Or maybe that wasn't the problem you are seeing.

Yea, those stuff were what I faced. Let me get rid of crossPaths for now.

I just released it and tested this script.

I at least see being ran fine in Travis CI ...

[info] Test com.databricks.spark.xml.JavaXmlSuite.testLoad started
[info] Test com.databricks.spark.xml.JavaXmlSuite.testSave started
[info] Test com.databricks.spark.xml.JavaXmlSuite.testXmlParser started

should not be a big deal .. I guess ..

Ok that's good. Either I made a mistake or something else was actually the fix. Thanks!
