Major refactoring

Fix memleak in KeyMap, fix memleak caused by loading a yaml file in
main.c. Change Copyright information. Rename functions.c and .h to
engine.c and .h. Take field and shape related functions to separate file
(still not all of them) and refactor them a lot. Refactor collision
detection. Add more warnings. Add sanitizer option commented out.
