Cleanup reference on jcifs-ext on core module

[bugeaud]

At this time, there is a reference on the core module to:

    <dependency>
        <groupId>org.jaaslounge.patched</groupId>
        <artifactId>jcifs-ext</artifactId>
        <version>0.9.4-patched</version>
    </dependency>

This version is not found in maven central. Thus it breaks automatic building.

• Download the jar file from SourceForge: jcifs-ext-0.9.4-patched.jar

• Install it manually in your local maven repository:

  mvn install:install-file -Dfile=jcifs-ext-0.9.4-patched.jar -DgroupId=org.jaaslounge.patched -DartifactId=jcifs-ext -Dversion=0.9.4-patched -Dpackaging=jar -DgeneratePom=true

• Finally, retry launching mvn install

Note that the artifact jcifs-ext-0.9.4-patched.jar is also in this repository, but not in the master branch: you will find it looking at the jcifs-ext-0.9.4-patched branch!
