Introduce pause mechanics, refactor a little

Introduce Pause mechanics and mention it in README.md.
Makefile: replace unnecessary "-MMD -MP" with just "-MD" flag, so it
allows to compile with tcc too.
Refactor: Rename game.isStarted field to game.started field. Move
arrKeys container to engine.c and remove it from main.c. Refactor char
iterator in utf8to32_strcpy function.
