Update pom.xml

I had a build problem with Maven, as a JAR could not be found.
After running the build with "mvn install -X" revealed the exception.
Two minor fixes in the pom.xml solved the problem:
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 17:22:22+0200)
Java version: 1.7.0_55, vendor: Oracle Corporation
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"

pom.xml default-jar --> cmd-jar

* renamed the id of the command-line app to 'cmd jar'.
  Wouldn't understand why the renaming causes build problems, and
  it frees the creation of a properly named default jar to be used by
  other programs as dependency.
