Hide default autocomplete for inputNode.
Handling venue submitting (when the user clicks)

- As before, trigger the venue_selected.fq_suggest event.
- Clear the inputNode (this may not be desired by everyone - maybe make it configurable?)
- Hide results and cleanup
Correctly binding the <enter> key to submitVenue.
Improving key events management

- Don't skip API calls and checks just because the pressed keys are not letters
- Ex: pressing backspace was not re-searching
- Hiding results and cleaning up if query < 3 chars
