CComponentsHeader: add possibility to show channellogo

Browse Source 
Contains methode setChannelLogo() with parameters
for channel id, channel name and optional
alignment (primary between title and clock). Default
alignment is centered.
Optional parameter to set logo height is available too.

Hope it works on first try. To see how it works, take look
at channellist class.
