Major breaking change to the structure of the format of the JSON, see the github for more details
Adds in the concept of waves, allowing for, well, waves of enemies to appear instead of one set of enemies and done.
Waves have most of the concepts the horde once had in them, such as how many enemies need to be killed, how many can be spawned at once, etc.
As such, each wave in a single horde can play entirely differently!
Adds in an optional boss phase for each wave
If boss entities are included, when the life count is depleted in a wave, and alternate boss bar also defined in the config will be displayed, and the wave will only end when the determined boss entities are killed
Depending on configuration, the normal horde can either continue to spawn, or not during the boss phase.
Hordes are loaded from a subfolder in the config folder now, again see the github for details
But, this means if you keep every horde in its own file, and one file breaks, every other horde should work fine.
