Table support for parametersbeforespawn

[greatbritdan]

Instead of being a boolean, if a "...parametersbeforespawn" is a table it uses that for the "...parameters" table instead.
Allowing enemies to pass parameters both before and after spawn, not just one of the other. More of a quality of life feature but not too much effort to add, would be nice...

Example:

"spawnsetparameters": [["x",2]],
"spawnsetparametersbeforespawn": [["qaudno",2]],
