* Add snail-mode map
* snail-mode: cap max hazards to 7
- Ensure that no more than 7 hazards are added to a square. This
fixes a bug where some squares were getting way too many hazards
applied to them. There must be some other bug at work here as
well.
- Change author names to be github usernames instead of first names
* snail-mode: fix bug with eliminated snakes
- Ensure that hazard snail-trail is not added for eliminated snakes
* Update from Stream July 31
Added comments to most functions and important bits of code
Also changed the map so that instead of a fixed number of 7 hazards,
we add hazards equal to the length of the snake.
* snail-mode: add TAG_EXPERIMENTAL and TAG_HAZARD_PLACEMENT
* snail-mode: use Point as map key
