Added improved hydra scaling (#795)
* Added improved hydra scaling Added min, max and trigger to config Added online_player_scale to config Made hail hydra chances a variable of: - number of online players (toggleable) - evolution based on a custom formula that has a slow scaling until evolution 0.8 * Removed debug game.prints * Backwards compatibility Added conversion from old config to new * Updated config to show -1 for unused * Added locking chance * Added improved hydra scaling Added min, max and trigger to config Added online_player_scale to config Made hail hydra chances a variable of: - number of online players (toggleable) - evolution based on a custom formula that has a slow scaling until evolution 0.8 * Removed debug game.prints * Backwards compatibility Added conversion from old config to new * Updated config to show -1 for unused * Added locking chance * Added behemoth-worm-turret * Removed old behemoth-biter * Added new default configuration
