- Realigned keyboard in settings menu

- Added controller support

Please note, that you can remap gamepad controls in Steam Input settings (it's extra0 to detonate, extra1/extra2 to change explosion size, and extra3 to change timer), but changes won't be reflected in UI. Technical limitation.

- Fixed code crashing after loading a quick save

- Added an option to remove collisions between C4 charges
- Tried fixing C4 attaching to player

- Fixed C4 being enabled at all breaking all custom weapon rotation

- In third person, your character should now correctly hold the bomb with both hands

- Fixed a bug where explosion happened at position where bomb was placed, and not at its actual position

- Made C4 actual physical object
- Most basic controller support (i.e. planting bombs works, not changing size or timing though)
- Changing keybinds menu now doesn't kick you out of the menu the moment you click on a desired key
- Cleaned up the codebase

- Fixed a bug where game wouldn't use custom detonation key set in the settings menu.

- Fixed default explosion size value being set to 100, instead of 4.
