first version of a ColorPickerView
rename ColorPickerView into ColorPicker
rename WiflyLight.View into WiflyLight.widget
first implementation af small gradient
implemented 3 sectors
use of ArrayList
implemented generic sector generation
TODO: set sectorWidth dynamically
completed vertical LinearGradient in ColorPicker.
TODO: match the calculated color better to the shown color
completed ColorPicker implementation for one dimensional selecting
implemented sectors with only one LinearGradient
started implementation of multiple lines for two dimensional selection
since a two dimensional selection is not efficent to implement right now, we optimized the one dimensional one to use only one gradient
simplified color picking by using an image
removed code for fast debuging (no scanning)
fixed UART_sendString()
the switch to the stdint types was good, but not for everything ;-)
