## Issue
6712 Comment Moderation - time based bans
## Approach
- Consolidated the 3 types of blocking buttons in the comment content menu (i.e. Block, Moderator Block, Admin Block) into 1 regular Block button.
- Show a modal when Block is clicked.
- Let user choose the blocklist.
- Let user choose the timeout duration (this PR's impetus).
* initial support for block/mute
* hide blocked + muted content everywhere
* add info message for blocked/muted characteristics
* sort blocked list by most recent block first
* add 'blocked' message on channel page for channels that you have blocked
* cleanup
* delete unused files
* always pass mute/block list to claim_search on homepage
* PR cleanup
