add hsvColor function

[ichan-mb]

Added support for defining color in HSV, using a function expression

Example :

<App>
	<Rectangle ux:Class="ColorSwatch" MinWidth="200" MinHeight="200" CornerRadius="10">
		<float4 ux:Property="Value" />

		<Rectangle ux:Class="ColorBox" HitTestMode="LocalBounds">
			<Selectable Value="{Property this.Color}" />
			<WhileSelected>
				<Change this.StrokeColor="White" />
				<Change this.StrokeWidth="2" />
				<BringToFront />
			</WhileSelected>
			<Tapped>
				<ToggleSelection />
				<DebugAction Message="{Property this.Color}" />
			</Tapped>
		</Rectangle>

		<Selection MaxCount="1" MinCount="1" Value="{Property this.Value}" />
		<GridLayout RowCount="10" ColumnCount="12" />

The build fails on AppVeyor, but looks like a spurious failure. Can you try recommitting and force-pushing to restart the build?

[ichan-mb]

OK, I've done it, now AppVeyor not report any error
