Formatted "DynamoView.xaml" to have an attribute on each line

This pull request changes only the formatting of ```DynamoView.xaml``` to have an attribute on each line (through auto-formatting key ```CTRL + K + D```). It is worth noting that few redundant attributes are identified by ReSharper and therefore, removed here (e.g. ```Grid.ColumnSpan=1``` which does absolutely nothing).

Hi @lukechurch, due to the nature of this change (being auto-formatted) and the extent of it, I'm merging this right in (in order not to confuse potential changes others have in the same file). I'm going to cherry-pick this over to ```Revit2015``` branch, please help to revert it if for any weird reason this breaks things. Thanks!
