#8 Add ability to get metadata using CtlProcessor

[Ricky Ng-Adam]

This enables the user to get metadata information without having to do offline instrumentation.

The patch adds a new CtlProcessor RPC command, metadata.get, which contacts the remote EMMA and generates a coverage.em file.

This is done using the following command:

java -cp emma.jar emma ctl -connect $HOST:$PORT -command metadata.get

This is followed by the existing command:

java -cp emma.jar emma ctl -connect $HOST:$PORT -command coverage.get

and the reporting command that takes both metadata and coverage information as input:

java -cp emma.jar emma report -r html -in coverage.em,coverage.ec -Dreport.out.file=coverage.html --sp [source paths]

(metadata + coverage = session data -> report)
