[00/03] Scorched Earth playable demo

Here I am uploading a demo version of our toy.
What is not in the demo:
- armor
- purchasing weapons
- recording the table of records on disk

The weapons in the demo do not end and not everything is given, although all types of weapons have already been implemented. Please note that the computer is not devoid of logic, although
the shooter is still quite stupid, but its stupidity is often
enough to defeat an inexperienced player.
Write responses! It's not too late to change anything (but not too radically)!

With respect, Roman.
