Add TitleID sort method

Adds an additional application list sorting method for the TitleID. A
bit of a niche choice for sorting but I think the TID is a relevant
enough piece of metadata that it should be there. (And I personally
would be using it)

- Using existing TitleId constant in ApplicationSort, implying this was
meant to be in the sorting options at some point?
- Reuses the "DlcManagerTableHeadingTitleIdLabel" locale for fulfilling
the need already, might be better to make a unique one for this in the
long run but this codebase is new to me so I wanted to make the changes
as unobtrusive as possible
- Using app.Id for the comparer seems to work fine, not sure if using
something else like IdString would be better?
