- CustomReactions module (and customreactions db table) renamed to Expressions. This was done to remove confusion about how it relates to discord Reactions (it doesn't, it was created and named before discord reactions existed)
- Permissionv2 db table renamed to Permissions
- Expression command now start with ex/expr and end with the name of the action or setting. For example .exd is expression delete
- CommandStrings will now use methodname as the key, and not the command name (first entry in aliases.yml). In other words aliases.yml and commands.en-US.yml will use the same keys (once again).
