[FR] Member download based on tags

[mm12]

Right now, you can download based on tags, or based on members. If the /users/MEMBER_ID/artworks/TAG_NAME is used, you can get a result of any of the member's works that have that tag. This would be useful.

if you want to get multiple tags, enter as 2 separate, then it proceeds as normal, but skips entries already fetched.
