Attaching Source

[Ming Fang]

Please consider attaching the Karaf source to the Maven Repository.
This will enable tools such as Intellij to automatically download the source 
code for Karaf.
Having the source is invaluable for both learning Karaf and when stepping thru 
code.
Below is what I usually put in my main pom.xml

            <!--attach source-->
                <plugin>
                    <artifactId>maven-source-plugin</artifactId>
                    <executions>
                        <execution>
                            <id>attach-sources</id>
                            <goals>
                                <goal>jar</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
