Shimul 8a10efaa01 Allow setting environment variables in whoogle.env (#237)
This allows the user to enable their preferred settings in a variety of
ways, depending on their deployment preference. Values added to
whoogle.env can be enabled using WHOOGLE_DOTENV=1, in which case all
values in the env var file will overwrite defaults or user provided
settings.
