More filters for the user search page

[andreoda]

About the user search page: https://vocadb.net/User?filter=

Currently we only have the options to search for:

• Name
• Group (user type)
• Knows language
• Artist accounts
• Show disabled accounts

Additionally, we have these sort options:

• Name
• Member since
• User group

---

Suggestion for the following search and sort options:

• Verified Email (yes/no) (available for mods only?)
• Email (available for mods only)
• old username/s (available for mods only?)
• IP (available for mods only)
• submissions count
• total edits count
• comments count
• tag votes count
• power count or level
• collection count (albums)
• liked songs count (likes+favos)
• followed artists count
• last login date/time (available for mods only?)
• last activity date/time (available for mods only?)

Additionally, there could be a new filter/statistic introduced: Amount of entry reports created
and then also added as a search option to the user page (available for mods only).

Another issue: the suer search page is missing the "More language options"
