QML API should be properly indented and color coded in a tablular form

[Nekhelesh Ramananthan]

The online API docs needs some UI rework to make it more appealing to developers. For instance, let's compare the current Ubuntu SDK documentation presentation in QtCreator (http://imgur.com/laQ0yif) and the online SDK API documentation (http://imgur.com/hXNc8ev).

-> The SDK Documentation in Qtcreator is organized nicely in table with alternate rows in different color. This makes it pleasing to the eye as one proceeds from one row to the next.

-> The Element and its description are in two different columns which are well indented providing a cleaner and more organized look. Also the element description is left aligned.
