**Improvements**
- Preformat and intent filters (configured through config file) were expecting "user_input" instead of "{user_input}", which was inconsistent with user_input logic in nodes. Now the user's input is always referenced using "{user_input}" no matter where it is referenced.
- Emily has always set user input to lowercase and removed all puncuation before matching it to patterns. Previously, when "{user_input}" was referenced in commands and responses, this formatted version of the input was used. Changed code so that now "{user_input}" is replaced with the raw input of the user, complete with capitalization and punctuation.
