Vehicle Hotkey Fix

[chrimchim]

Summary

SUMMARY: Bugfixes "Skips over reserved keybindings when creating a list for which tank to fill when interacting with vehicles"

Purpose of change

#26467 - Unable to use certain hotkeys when accessing filling tanks from the vehicle interaction menu.

Describe the solution

Uses simple logic to skip over certain keybindings that do not work when pressed.

Describe alternatives you've considered

Finding a way to make these keybindings usable in the fill menu, though I was unable to do this since I couldn't find what was using them

Testing

Created a vehicle with over 30 tanks to test very large hotkey lists, identified hotkeys they were unresponsive and skipped over them. after the normal hotkey list finishes the list moves into capital letters of which none are usable. I'm not sure how to fix this, so it may be a concern in the future.

Additional context

N/A - Fairly simple change.

Maybe better this code?

while( hotkey == 'c' || hotkey == 'g'|| hotkey == 'j'|| hotkey == 'k'|| hotkey == 'l'|| hotkey == 'p'|| hotkey == 'q'|| hotkey == 't'|| hotkey == 'v'|| hotkey == 'x'|| hotkey == 'z' ) {
hotkey += 1;
}

Please do not forget to run Astyle for this code.

What happens if a user reassigns the specified keys in keybinding menu? Please test it.

There's a strange interaction with global keybindings. If you overwrite a global binding, it will cease to function in the vehicle fill/siphon menu. I'll keep testing to look for problems.

Secondary findings (edit):Completely removing a global binding doesn't have any affect on the menu, only overwriting the preset bindings disrupts bindings in the fill/siphon menu. Re-inputting these bindings resumes normal functions in the refill/siphon menu.

Tertiary findings (edit): When using the original code changing or overwriting the nonfunctional keys does not affect whether or not they work in the fill/siphon menus
