Intellisense + debugging capabilities for Selenium scripts

[verycoolgreg]

Now that ReadyAPI is supporting Selenium Webdriver, it would be really helpful to support development effort when building new testecases.

Currently, when working with Selenium libraries, the editor feels more like a plain text notepad. 

Suggested improvement: Add IntelliSense and debugging capability during runtime, as it's extremely hard to find where the script is failing.
