* d_s_room / d_s_name debug work

* camera_class rtti fix

* d_a_title debug / handle shield rel changes

* fix shield build

* fix regressions

* Wrap >4-char literals in a MULTI_CHAR macro

Modern compilers do not support CW's non-standard behavior with
>4 char literals. We can, however, use a constexpr function to
compute the u64 values directly. This leaves <=4 char literals
unchanged.
