Proposal Add ColorPicker Control

[insinfo]

The ColorPicker is an editor that allows a user to pick a color from predefind color palettes. By default, there are 140 available colors and 10 predefined standard colors. You can use your own custom color palettes by setting the AvailableColors and StandardColors properties accordingly. You can also get/set the recently used colors by using the RecentColors property. Types Ring, Pie, Palette, Hue, Bar

<ColorPicker Name="ColorPicker1" SelectedColorChanged="OnChange" Type="Pie" ShowPalette="true" ShowColorSpaces="true">
       <Options...></Options>
</ColorPicker>

I updated with some syntax example and type definition, if you want to add options or types of colorpicks

At http://clipflair.codeplex.com/SourceControl/latest if you go to Client/ZUI/ColorPicker in the tree (will probably move to separate github repo) can find a color picker that shares xaml+code between WPF and Silverlight. Probably bit old fashioned, but still useful to see the project structure used for sharing xaml+code, it sure was possible before UWP came with "using" and other breaking changes or omissions

@birbilis Good news, I did not know that, thank you for the statement

It would be nice if it were added in Xamarin.Forms and WPF as well
