Change the way config files are parsed

[F0xedb]

Currently, we need to suffix the config file with numbers e.g. float_1 and float_2 which is rather bizarre.

It would be better and more useful (both from a dev and a user perspective) to support a config as such:

float = "a"
float = "b"
float = "c"

And generate the following lua representation:

local config_value = config.parse("your_config_file")
for floating in config_value["float"] do
    print(floating)
done

Which prints out all values (a, b, c)

By treating every unique element in the config as a list we can omit manual numbering (which is annoying when reordering things like plugins)

This should be fixed
