To-do list

Add tests for indent, dedent and remove-line-break motions
Add normal-delete tests for each motion, checking that searchList is as expected
Add tests for other yank motoins
- Tests should be based on existing tests for delete-motions, and in the same order.
Bind gamepad functions from GLFW and/or RGFW
Add tests for NormalYankDelete functions, to make sure that they are yanking the expected string.
