Update promos

[megalon]

Updated promos logic to allow for up to 3 links per promo, and updated the YUR promo for the new format.

This implementation is a bit gross, but this is the best way I could get this to work correctly.

In the future it may be worth using a more elegant solution, but it doesn't seem like this type of styling is easy to dynamically generate in this situation. My knowledge of WPF is limited, so there may be an easier way to do this that I've overlooked.

Before anyone tries to go down that rabbit hole like I did, here's what I tried:

Access the mod's StackPanel directly to inject the promo elements when needed
It is possible to find elements by name using rootElementName.FindName("nameToFind"), but the element would need a unique name in the list.
Unfortunately, it is not possible to set the name programmatically through xaml, such as with Name="{Binding ModName}" .
I think this would be possible if the xaml for the list were generated from the C# code, but it would require reworking a lot of MA.

Using a different WPF element other than TextBlock
Using a different element still runs into the same issue as above, and the hyperlinks would still need to be their own child elements.
