Add the ability to triple click text boxes to select a whole line

I hate the way I had to implement this. TL;DR we have to define it within every page/window it is used since defining it in app.xaml breaks the default visual template.

Thank you! I didn't expect it to be pretty, but I didn't realize it would require so much copypasta.

Ideally it should have just been used once in app.xaml but apparently templates don't behave correctly in that situation? So unfortunately it had to be a lot of copypasta, though it's still better than manually applying the property to every instance of a textbox.

Yup, I understand the compromise in the solution and I wish knew why it doesn't work in app.xaml, and I do not know.
