[Registry-dev] Major UI code refactoring and clean up

[Chathura C. Ekanayake]

I am doing a major improvements/refactorings to the UI logic (both Java 
UI backend and JSPs). This will improve the modularization of UI code 
and make it easy to enhance the custom UI features, which I am currently 
working on.

It is better if you can keep the changes to the UI code (webapp module) 
minimum during this period.

Thanks,
Chathura
