Title: Treat command line "-c" option number config values as such (STORM-173)

This fixes the `ClassCastException` when submitting numeric config values using the `storm` utility's `-c` option.
It works by first checking if the `-c` configuration value is numeric (via Apache Commons' `NumberUtils#isNumber`) and, if positive, converting it to a numeric type. See STORM-173.
