113 submission form passes placeid to back end

[Tinxte]

Summary

• On submission form, Google maps Autocomplete API no longer makes excessive calls; should be no more than 3 API calls per input change
• Selecting a Google address populates address and grabs the placeId for that address
• Submitting will save both address and associated placeId to database

Notes:

• You may confirm Place ID's for testing using Google's PlaceId finder. https://developers.google.com/maps/documentation/places/web-service/place-id
• You may also uncomment line 79 on SubmissionForm.jsx to preview form values.
• Issue #121 created for additional validation to ensure users select a Place address
