- configure_input_player_widget.cpp: always better to use `const auto &`
whenever possible
- profiler.cpp: `ev->pos()` is deprecated, replace with
`ev->position()`, which returns floats, thus the addition of
`.toPoint()` (same as what's happening in `pos()`)
- game_list.cpp: `QString::SplitBehavior` is deprecate, use `Qt::`
namespace instead
Allows reporting more cases where logic errors may exist, such as
implicit fallthrough cases, etc.
We currently ignore unused parameters, since we currently have many
cases where this is intentional (virtual interfaces).
While we're at it, we can also tidy up any existing code that causes
warnings. This also uncovered a few bugs as well.
Moves includes into the cpp file where necessary. This way,
microprofile-related stuff isn't dumped into other UI-related code when
the dialog header gets included.
