Add STscript returns, role changing, and aliases

Adds the following STscript changes:
-Returns to all commands and makes arguments optional
-before_scenario option for chat insertion position (to match UI)
-/note-role to change the chat insertion role
-/note- Aliases to all commands so they're centralized
