Title: Added support for reading api key and shared secret from config file

Fixes issue #6

This change allows the api key and shared secret to be read from _config.yml while still also allowing the environment variables to be set. Environment variables will override the values in _config.yml if both are set

Example:

```YAML
flickr
api_key:
shared_secret:
```
