2 - Customizable Chat Style/Colors

[snade]

I rolled back the default style. Please, see if the messages are still cropped. Added more custom colors, and the "color button" is little improved. There is the KColorButton class, and maybe we should use it when USING_KDE. I really dont know if the styles are nice. Please, help me with that :-) I have also rolled back the history layout. Fortunately, the history list colors is customizable as the chat colors are. The tab color while using is typing is also customizable now. Any comments, please, let me know :-) thank you all.
