Can now export Recipe Book in json format to sdcard for use in other apps
Recipe Book no longer exports if there are no recipes
In a way better place for the imgur upload, proper images are being
sent. Just need return address.
Posting images to imgur is now implemented using an asynctask, simply
create a controller object, use it to call the post method (sending it
the string path of the photo). Could use some prettying up and the
reverse operation (saving an image from a url) needs to be implemented,
but that's easy mode.
prototyping for fetching image from url
Post to imgur and Fetch from url are complete, the format of the fetch
return may need to be adjusted to match image viewing requirements but
it's easy to change.
Merge remote-tracking branch 'origin/master' into imgur
Added testing prototypes
Added a constructor that makes more sense
Fixed the post method instantiation and example code
Updated the return fetch to return the same path as is stored in the
Photo class (the absolute path).
