[Enhancement] Allow to change the Reveal Icon in the PasswordBox

[gigios]

I searched in the repository if was present a solution on my problem.
I want to change the 'default' Reveal icon used in the PasswordBox with the 'standard' icon used in Windows 10.
From:
To:

It's clear that I can replace the PasswordBox style with a my custom style but, probably, the best solution could be the implementation of a new attached property in the PasswordBoxHelper in the similar way of the CapsLockIcon property.

Do you think that could be a good solution?

Thanks for the support

@gigios I will changed this

MahApps.Metro/src/MahApps.Metro/MahApps.Metro/Styles/Controls.PasswordBox.xaml

Line 775 in 94d476b

Style="{StaticResource RevealButtonStyle}"

to DynamicResource, then you can override it with your own style.

MahApps.Metro/src/MahApps.Metro/MahApps.Metro/Styles/Controls.PasswordBox.xaml

Lines 39 to 69 in 94d476b

	<!-- Button Style for Win8MetroPasswordBox -->
	<Style x:Key="RevealButtonStyle"
	BasedOn="{StaticResource ChromelessButtonStyle}"
	TargetType="{x:Type ButtonBase}">
	<Setter Property="Margin" Value="1" />
	<Setter Property="Template">
	<Setter.Value>
	<ControlTemplate TargetType="{x:Type ButtonBase}">
	<Grid Background="{TemplateBinding Background}">
	<!-- Material - Eye -->

Ok! Thanks
In this way it's possible override a small portion of the 'original' style.
