Implemented all the DB functions except the erasePhoto(photo)

- implemented all function such as getDays(), inserNote(), removeNote
etc.. except for the deletePhoto() function
- Added in onCreate() the creation of the mood table
- Inserted values in the mood table ( This can be done better, rather
than do it in the onCreate() )
Implemented Photo contructor

- For now it work with just the path String (maybe necessary an Id)
- Missing temporization and canBeDeleted() and canBeUpdated() methods
- Missing Thumbnail methods
Implemented Note constructor
Changed int Id with String Name in the MoodInterface class

- Just changed the constructor input type
Implemented Mood constructor and methods

- The constructor is implemented to receive only the Name of the mood
and associates it to the right path
- MISSING: the Path string of the mood images
Some fixes related to the constructors of the Mood Photo and Note
implementation
