Ajax Integration

Adds in a basic ajax command for submitting posts (using jQuery)

Current issues: 
- [ ] AJAX the retrieving of shouts??
- [ ] Currently just console logs are done if there is an error message from the AJAX - we need to do something more clearly (potentially might have to be a second AJAX request to log it through JLog)
- [ ] We need to display the Error message when there is an error
- [ ] Date runs on UCT when AJAX post runs (database correct however)
- [ ] Add in the AJAX as a 'beta' (on by default) for the first release???
