Add javadoc comments to source classes
CB-5471: add deprecation javadoc/annotation
CB-5490: add javadoc target to ant script

- add javadoc target to ant script. It must be invoked explicitly to run.
- ignore the generated javadoc html directories.
- clean up javadoc errors in source files.
- upon invoking 'clean' target, erase generated jar and javadoc
Thanks for Benn Mapes for making this process easy.  Updating the Android API level.
CB-5422: Don't require JAVA_HOME to be defined

JAVA_HOME is not necessarily defined on Linux and Mac.
Print out the value of JAVA_HOME in the error message
in case "java -version" fails.
Moving the console.log out of run() method

Since cordova-cli calls the check_req library run() method, we do not
want to always console.log on success in there (not usually a useful side
effect).
