MergeResults now works from CMDLine tool

Hi,

MergeResults now works from CMDLine tool. It requires merge-results.properties file which can be found in JMETER_HOME/bin dir.

java -jar CMDRunner.jar --tool Reporter --generate-csv test1-test2.csv --input-jtl merge-results.properties --plugin-type MergeResults

We have finished our changes for this version, we'll see later for the last two features, I don't have time right now!

Regards,
Félix H.
