Add Modscanner support to Chatterino

[Walledgarden]

ModScanner is a platform, which offers users the ability to query and retrieve detailed information regarding any user on Twitch. The page provides users with insights into the selected channels, where the selected user is currently moderating, VIP, and founder. Also, ModScanner displays the users relating to a specified channels like the moderators, VIPs, and founders for the channel-sight as well.

Including a button at the profile card in Chatterino that redirects users to the ModScanner page can provide huge advantages. By using this feature, moderators can enhance their ability or normal users can learn more about a specific user to fulfill their job by gaining in-depth insights into a given user's involvement and roles within the Twitch community.

In the past, there was already another Lookup for Channel Moderators, which provided very good utility to the Twitch users, but was sadly shutdown recently, so we decided to make up our own page.

This is an example of the User Lookup page on https://modscanner.com/user/cupofeggy (or https://mod.sc/cupofeggy)
