Added /canteen/id/:id route (plus optional distance calculating on the server)
Changed json key names to lowercase and removed useless json function for location
Started working on a method to change the user avatar...
Cleanup and further improvements: Will now upload the image to cloudinary servers, redownload it in a smaller version and calculate the base64 of the smaller version.
Avatar uploading works! A bigger version (max 512x512) of the avatar is saved and linked in the database. And a smaller version (64x64) is retrieved and saved as binary data in the database.
