Bug fix server.js

Application was breaking as comma seperator was missing between parameters 'application.get('ip') and callback function.'
Bug fix 'routes/index.js'

Object reference 'request.application' was not defined, changed it to 'request.app' which is defined correctly. Now the route '/data' does not break
Bug fix 'application.js'

Application was not able to log in 'server.log' and 'router.log' as appenders array was defined as applicationenders, after this change application was able to log to these files

Also renamed the log file from 'route.log' to 'router.log'
Add logs folder for tracking

The 'logs' folder was added for tracking to include it on 'prod-cahsy.rhcloud.com' server as the application logger was throwing an error

This is just a quick fix, have to find another solution soon.
