Rewrite the IRC Bot Application to Improve its maintenance and stability

Several issues:

• It's currently broken since we modified the Component Manager behavior (it now compares Roles on the Role class and no longer on the class name). Everytime we define a new class in Groovy, it's a different from previously defined classes and thus they're not equal, which makes the IRC Bot app fail when trying to look up IRC Bot components.
• There's a lot of Groovy and it's hard to maintain
• Requires Programming Rights (not a big deal)
• Hard to add new Botlets
• Heavy (includes the PircBot jar in the page, creates a lot of unnecessary classes, potential memory leaks since the Classloaders are help in memory and not cleaned)
