Currently,with Settings Panel, we can change the time format and username.

The Fonts list is now available to the end user for changing the Greeting message. Howeve, the Seetings Panel doesn't look good currently.

Currently, all the 4 features of Settings panel are working. However, there is some glitch with its appearance.

I have added cookies to remember the user's all prefernces(time format, font, background color). Also, the font list is appended only once. The appearance has been optimized to look decent.
