depctrl global config: use depctrl's config handler

better than finding a file that's probably the config, parsing the json, and writing it back in,
for obvious reasons

turns out no i wasnt thinning out the soup too much
twas just right

Reason for adding values one by one in key-pair loop instead of just config = new_config:

> [01:31] arch1t3cht: oh, I think you can't assign entire tables to DependencyControl.config.c
> [01:31] arch1t3cht: like, you can't do DependencyControl.config.c = <my new config>,
>                     you should do DependencyControl.config.myfield = <my new value> and whatnot
> [01:32] arch1t3cht: because behind the scenes it uses metatable magic to track what field changes
>                     so it can merge its own changes with ones that other scripts made in the meantime
