Could not find some imports on macOS.

Use game controller APIs instead of the joystick ones to be able to use
the gamepad button DB file.

Changes to character rigging. Also CMake now respects ini-config
structure (although in the future, the lib file should be used. Check
installation in CMake for macOS/*NIX).

Use appropriate syntax and names for config logic.

Define separate package for config code.

Ensure input test implementation is aligned to current input API.

Add context on all log items.

Put mocks to directory structure mimicking project structure.

Use abstraction instead of using SDL dependencies.

Fix CMake lib dependencies for crypto/SSL. Also ensure websockets work on macOS for both client and server.

Come up with our own logging system.

Include _s wrappers for most standard function calls.

Properly parse joystick GUID on initialization.

GUID config is used for gamepad processing.

Add compatibility for macOS and *NIX files

TODO: inspect building of dependencies

Add custom enums for making sense of returned values from config and
game app code.

Add templates for config item types.

Also updated server's config to use the global config module.

Remove symlinks and make codebase use common modules instead.
