SplitView Pane enhancements.

[chrisleyva]

1. The SplitView pane is now closed when selecting the previously selected MenuItem.

2. The swiping gesture logic has been fixed to improve the experience of using the swipable SplitView.

I also fixed up the comments in ManipulationCompleted. :-)

I just added punctuation and capitalized the first letter of each. I only modified the comments in that method since it's the only method I modified.

But really nice work on this control. I really like the use of the ListBox, too.

Thanks! But looks like the changes you made in the ManipulationCompleted breaks the up and down pan gesture. :(

Also I'd like to keep the code in Shell.xaml.cs and ShellViewModel.cs intact 'cause I actually borrowed them from here.

[chrisleyva]

Sorry. The up and down pan was working for me :-(
I tested it quite a bit and I feel like it behaved smoothly.

Also, the link you posted is dead.

[JustinXinLiu]

Sorry, just updated the link.

Try this:

1. Open the pane and pan to select the last item;
2. Open the pane again and try to move up your finger just a little bit.

You will notice that the very top item gets highlighted, which is wrong. The 2nd last item should be highlighted instead.

I'll give that a shot. But before my changes, I noticed that both the up/down pan and open/close swipe behaved in an unusual way.

I'll take a look a bit later and see if there is a way to redo my fix without modifying Shell/ShellViewModel and without breaking the up/down pan.

Thanks @chrisleyva ! Appreciate your help on this.
