Add tags to UiStack (#4617)

Browse Source 
You can now set custom tags on the `UiStack`. This allows you to write
code that is situationally aware at runtime. For instance, you could
decide wether or not a label should truncate its text depending on what
part of your ui it is in, without having to pass that info down via the
callstack.
