Images downloaded from zerochan aren't named correctly

[Roshri]

Bug description

Tried to switch from some of the boorus to zerochan to get some stuff and when I downloaded the files I saw that it doesn't work with the same tokens as the boorus. %artist% %copyright% and %character% don't work at all since everything was listed as the default for unknown sources.

Steps to reproduce

1. Select zerochan as source
2. Search anything and download with preferred naming (mine is %artist%\%copyright%\%character%_%date:format=yyyy.MM.dd-hh.mm%_%md5%.%ext%)
3. Check if the file was named properly

That would be because Zerochan doesn't use the same namespaces as other sites. Mangaka for Artist, for instance. Copyright can be a variety of things, character is the same.

[Roshri]

That makes sense, so artist and copyright are out of the picture, I think I can get a workaround by refining searches and then telling grabber to download to a specific directory to keep my naming.
But it is still not pulling character correctly, I only get unknown_md5.ext
But if zerochan is that much different than the boorus then there's probably no workaround for this

There should actually already be some pre-built tag type mappings for Zerochan and a few other sources to work without needing to have to work around them. Those mappings are:

• idol => model
• series => copyright
• mangaka => artist
• game => copyright
• studio => circle
• source => general
• character group => general
• oc => character

However, it would seem that they have been broken in a recent update. I'll push a fix ASAP to solve this.
