    Fix for TOREE-430

    To fix TOREE-430, REPL-generated classes must be made visible to a 
classloader.
    
    The only working way I found is to set the `spark.repl.class.outputDir` 
system property (and subsequently the corresponding Spark configuration 
property) to a path to an output directory of a REPL compiler. To achieve that, 
I had to move `SparkIMain` initialisation before creation of `SparkContext`.
