JSON changes

Some of the changes were sparked by thoughts about how I’m going to create save states. I came up with the idea of something like this:

"entities": [
    { "chest", [ x, y, opened... ] },
    { "person", [ x, y, ... ] },...
]

You would read the name and use toptr something like:

= name (json_get_string json "entities>[0]")
= name (string_format "create_%" name)
var ptr
= ptr (toptr name)
; create a vector from the array after "chest" /etc, which can be fully automated
var entity
call_result entity *ptr vec
vector_add entities entity

Now the load code doesn’t need to know about the types. Typically you see:

if (type == chest) {
}
if (type == person) {
}
; a million others

By the way, if you use this trick, it won’t work if you obfuscate your code. I can allow it though through a command line switch to list your create_ functions/etc.
