Drag and drop ruby Merged

The ability to drag and drop ruby scripts from the file system into the ICM window in order to execute them. This will not only be useful for day to day use of using ruby scripts but will also be useful for 3rd party (and open source) applications like InfoLab https://github.com/sancarn/InfoLab Currently in order to inject ruby scripts into the UI we have to use open up Network tab and execute the "Run Ruby Script" button's default action. Creating a drop event onto ICM would be significantly easier and is extremely easy to implement (a few hours)
