Add XML layout wheel-dependent parameters

[GoogleCodeExporter]

Add the possibility to set visible items count declaratively (in the XML layout 
files) like this:

kankan.wheel.widget.WheelView android:id="@+id/day" 
some_namespace_prefix:visibleItems="1"

This is an example. I meant that it would be great to have an abilities (like 
of a "regular" android widgets) to customize views.
That is I think it is possible to unite this issue with some others like this: 
http://code.google.com/p/android-wheel/issues/detail?id=13 etc. 

P.S. Thanks for widget. You have done great work already.
