Support TabStripPlacement property for TabControl

[leMicin]

Problem

Currently, when we try to put TabStripPlacement="Left", the result is very off.

Solution

It would be awesome if Adonis could handle other TabStripPlacement than "Top".

Alternative

We currently have put a patch in place in our project to detect the TabStripPlacement. Here is the bit of code that we have put in place:

    <Style
        x:Key="{x:Type TabControl}"
        BasedOn="{StaticResource {x:Type TabControl}}"
        TargetType="TabControl">
        <Style.Triggers>
            <Trigger Property="TabStripPlacement" Value="Left">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type TabControl}">
                            <Grid KeyboardNavigation.TabNavigation="Local">

                                    <ColumnDefinition Width="*" />
                                </Grid.ColumnDefinitions>

                                <TabPanel
