Handle login from anonymous playlogger

When user logs in on the site, the sign-in credentials are changed, so we should drop the old credentials and no longer playlog them.
Return empty tables as empty JSON arrays

Rather than empty JSON objects. Generally this is what I want. Also an empty array is an empty object in JavaScript so accessing non existent properties will work the same, while also allowing me to call e.g.: map on the empty array.

Currently lua-cjson returns {} which has no native map, leading to exceptions unless I check types first, which clutters the code.

Ideally Lua would differentiate arrays and hashmaps so this would just work :P
Don't save every resolution during queueing

* It's excessive since our save format is JSON and not something with partnerIDs efficiently segmented in the file format
* We are dumb and have no synchronization for saves, so saving this frequently was quite often causing corruption in the end JSON.
Preventative code
Allow callbackID on string JSON commands
