## Description of change
Add `Reset All` buttons to these tabs which clears out bindings to none
/ default.
For keypads, introduce a special `Use Preset` button which lets users
pick between numpad and top row number keys.
Update UI-visible string used for vKeys, especially the numpad ones
(e.g., `.` is now `Numpad .` to distinguish from the regular `.`
period).
Breaking change: if the user never had `P1 Keypad 00` set, the default
will change from `Enter` to `Numpad -` since both enter keys trigger the
same. This will affect a small number of popn/ddr players. They can just
change it back.
## Testing

## Description of change
Occasionally we would read a bad "vKey" for an analog axis and end up
accessing invalid memory (beyond the size of a vector) and potentially
crash or read junk values.
## Testing
Fixed based on minidump, this was a rare repro though.

Fixes#139
## Description of change
Add an option for detecting window focus when accepting input.
The new default will be to have the following:
* naive bindings will check for window focus
* rawinput binds are not affected, will continue to be accepted
regardless of focus
Other options (always / never choices) can be picked by the user to
tweak the behavior if needed.
Clean up usage of `0xff` constant to represent invalid naive vkey.
## Testing
Still in progress, especially in regards to performance.
On a i7-9700 system, 10000 calls to `superexit::has_focus()` takes
250-350 microseconds, so this should not be a big deal at all.
