Release v3

We've officially released a 3rd version of the tool! This update doesn't change much in terms of how it looks to users, but it has received a number of updates under the hood

• It should now be easier to change what events you subscribe to and what those alerts look like
• As part of above, the client (aka browser) is no longer in charge of building alert text
• Custom channel badges are now supported fully

We've also updated the readme with some more info on customizing the tool ✨
If you're using this tool, feel free to update and make all the changes you'd like :3
