Create enumerations for keyboard and mouse buttons

[victordmontero]

Scope

The goal of this issue is to crate enums for keyboards and mouse buttons and maybe you can include joypad buttons as well.

For SDL you could:

• Map SDL_Keycode constants values to an enum, in the case of the keyboard
• Map **SDLBUTTON*** constants values to another enum, in the case of mouse button press
• Map SDL_MouseMotionEvent constants values to an struct, in the case of mouse button press
• Map SDL_JoyButtonEvent constants to a enum, in the case of gamepad
• Map SDL_JoyAxisEvent values to an struct, in the case of gamepad
• Map SDL_JoyDeviceEvent values to an struct, in the case of gamepad
• Map SDL_TouchFingerEvent values to an struct, in the case of touchscreen

Additionally, other information about the input device should be sent alongside with the event data, like the device id, to distinguish between devices, for example if you have more than one gamepad plugged in.

Information about these events can be found at the SDL Wiki

DOD

• Ideally should have tests and be covered by coverage.
• Must have static_assert for every value of the enum

The SDL_TouchFingerEvent events where left out, for another issue
