Ref issue #58 - Using remote rsync path on options

[LeandroFranciscato]

it'd be used like this:

rsyncConf = {
        progress: true,
        incremental: true,
        relative: true,
        emptyDirectories: true,
        recursive: true,
        clean: true,
        exclude: [],
        remoteRsyncPath: "/home/user/bin/rsync"
    };

It could be helpfull when you're using a share server and have no access to add rsync to /usr/bin folder.
