Optional show hidden LayoutAnchorable on hover

[corytodd]

For our use case we would like the option to not auto-show a LayoutAnchorable
on mouse over (via mouse enter). This adds a new property to provide an option
to disable the auto-show behavior. Serialization support included.

Is there a better way to handle this?

Hi Cory, your suggestion looks good to me but can we please make the following adjustments:

1. set the default value of the CanShowOnHover="False" (so others are not put off by this new default behavior)
2. could you please decorate some items like the new property with a meaningful comment so we still know what this is doing when we look at it in a few months?

Otherwise, I think this is good to go, thanx for your contribution :-)

Thanks for the fast response!

1. I think we are respecting the default behavior by setting the backing field to true? I agree that we would want to maintain the current behavior by default which this does. Let me know if I'm misunderstanding what you're asking.
2. Will do, wasn't sure if you prefer PRs to "blend in" with the existing code or you like comments. Going with the latter :)

Sorry about 1. - I made a mistake here :-) so you are perfectly right and I was perfectly wrong, thanx for you patience
