Breaking 3.0.0 changes

This is an issue to keep track of breaking changes that I would like to see go into the 3.0.0 release. I am open to additional suggestions as well:

• Card defaults its VerticalAlignment to Top. Suggest defaulting to Stretch.
• Flipper defaults its VerticalAlignment to Top. Suggest defaulting to Stretch.
• Remove obsolete PalleteHelper methods.
• Remove obsolete members in SmartHint
• Remove obsolete DialogClosingEventArgs.Content. Use DialogClosingEventArgs.Session.Content instead.
• Remove unused DialogClosingEventArgs constructors
• Rename MaterialDataGridComboBoxColumn to DataGridComboBoxColumn. Since using the custom column in an app will require specifying the namespace, having the Material prefix adds very little.
• Vertical alignment of Label, TextBlock and TextBox should have VerticalAlignment=Stretch, and VerticalContentAlignment=Top
• Source code is no longer included in the NuGet package.
• MaterialDesignToolBar no longer sets FontFamily to MaterialDesignFont
• Popup in default DialogHost template no longer sets FontFamily to MaterialDesignFont
• MaterialDesignTitleTextBlock => MaterialDesignHeadline6TextBlock
• MaterialDesignHeadlineTextBlock => MaterialDesignHeadline5TextBlock
• MaterialDesignSubheadingTextBlock => MaterialDesignSubtitle1TextBlock
• MaterialDesignDisplay4TextBlock => MaterialDesignHeadline1TextBlock
• MaterialDesignDisplay3TextBlock => MaterialDesignHeadline2TextBlock
• MaterialDesignDisplay2TextBlock => MaterialDesignHeadline3TextBlock
• MaterialDesignDisplay1TextBlock => MaterialDesignHeadline4TextBlock

labels textboxs and textblocks have different VerticalAlignment by default and if you put them in stackpanel next to each other they won’t be on the same line

<StackPanel Orientation="Horizontal">
        <Label Content="Label"/>
        <TextBlock Text="TextBlock"/>
        <TextBox Text="TextBox" Width="100"/>
</StackPanel>

@csutcliff you can’t mix and match MahApps 2.0 and MaterialDesignThemes.MahApps which should only target MahApps 1.6.0

To say it in another way: No work has been put into MaterialDesignThemes.MahApps to update it to NetCoreApp or target MahApps 2.0
