Take and view photos.
Choose OR take an image, instead of both
Fixing lint errors
Removed extra images created through lifecycle activities

Many bugs associated with the lifecycle were fixed. Particularly:
- No images are created when backing out of the Add Recipe screen
- No extra images created when taking multiple photos
- No extra images created when switching between chosen and taken images
Resetting recipe data also deletes associated images. Fixes additional bug in life cycle.
Since I seemed to forget my variables were static, capturing an image, then adding an image overwrote the last image.
