Provide support for XInput mappings.

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.

Rename files in order to prepare for extraction for publishing
subsystems independently.

Put input and video subsystems into their own directories.

Update documentation.

Update identifiers to be consistent.

Make server optionally have a mountpoint for putting assets.

Attempt to connect client to server.

Ensure mounts are configurable.

Update initialization method.

Add libwebsockets client to game executable.

Delegate the event handling solely in input state.

Add tests for initialization and teardown for all input methods.

Specify describe block for each player tests.

Add memory and data-related implementations for handling game data.

Correctly dereference pointers.

Update input tests.

Declare memory before processing.

Declare variables early on.

Use short names for int types.

Provide default states for input and output.

Allow MIDI input to be filtered through MIDI channels.

Use higher bits of first message byte to get notes from all channels.

The game now uses MIDI support for alternative input methods.

Put I/O values to their respective structs.

Isolate input items into their own directory.

Ensure joystick direction enum names are consistent.

Ensure correct arguments are passed.

Determine config path only once.

Ensure one type of test can only be handled at a time.

Implement tests for joystick axis, hat, and button events.

Add third-party mocks, specify mock files.

/? Do we need first-party mocks in their own files, or can we provide a
mock flag in the implementation files already?

Make device handling opt-in.
