This is a huge aggregated commit. Basically I merged all changes I made to the project at work since June 2013.
I've selected few commit entries that might give an overwiev what was changed

    jmeter-ec2.sh:
        added new flags to define log_level for local and remote jmeter instances
        added new cfg flag: ${cfgJmeterLogLevel} that allows to set the jmeter's logging level (it modifies jmeter.properties file in the project's root folder). This file is later on uploaded to all load generators
        added new flag: ${cfgCreateGraphsForEachLoadGenerator} that toggles the step that generates individual graphs for each of the laod generators
        added support for new flags:
            cfgCreateAggregateCSVReport
            cfgCreateMergedFileForJenkinsPerfPlugin
            cfgGenerateAggregatedResponseTimePercentilesReports
            cfgCreateMergedResultFile
        added a fix, that checkis if any on remote JMeter instances didn't stop unexpectedly with an error msg "Fatal error, could not stop test, exitting" in the jmeter log. This should help to prevent jenkins job running infinitely when something like that happens.
        added info about the test duration
        added an option to disable HTML report generation
        added an option to disable proccessing of jenkins.xml files
        added new option to show last 10 lines of remote JMeter logs. cfg flag is called cfgTailRemoteJmeterLogs
        from now on all the *.out file are added to the results.bz archives

    download-jmeter.sh: added commands to delete downloaded zips

    resources/reportFooter.txt:
        fixed broken closing h3 tag

    resources/reportHeader.txt:
        added an option to show thresholds and aggregated report under two new top menu buttons

    checkMetricsThresholds.sh:
        added support for new thresholds: Throughput Bandwidth StdDeviation
        added an option to archive the thresholds file in the defined results folder. the archived file name will be thresholds.csv (helps to show it in the report)
        updated JMetere-plugins to latest 1.1.2 version whcih includes a fix in autostop plugin that prints out the reason it stopped the test in the jmeter log!!!

    install.sh and download-jmeter.sh: updated URLs and improved error handling
