front-end improvements, started back-end script

- commented out dev code
- added success function to ajax call, will place returning data from
backend inside #outputText as intended, not much left to do in front
end.
- set up functions to synonym/antonym returns, not actual algorithm,
returns hashed string just for fun.
- wrote routing code in spinner folder, will call either synonym or
antonym string depending on action variable, echos out returned string
from the function.
- also set the content type of the routing folder to text/plain.
