changed UI of help and FAQ sections

[jaivsh]

Description

The UI of "Help" and "FAQ" sections were primitie ones and lacked coherance with the rest of the application. I've changed the overall design and look of the page so that they become in-sync with the rest of the application.

Fixes #354 Fixes #356
