Added utility methods `addOption` and `addOptionsList`.
`addOption` checks if if option exists using `grunt.config(optionName)` method, and adds it to a list of options prefixed by `--`.
`addOptionsList` adds options in sequence and returns an array of options.
Using `addOption` and `addOptionsList` to automatically check and add properties.
Added support for all properties in `jasmine-node` module
Added support for parameters with values
