[Feature] Change contact picture

[vcasadei]

Is your feature request related to a problem? Please describe.
No, it's a new feature

Describe the solution you'd like
When creating a new contact, the same default placeholder picture is assigned to all contacts. I would like to be able to replace this placeholder picture with a new picture of my choosing.

Describe alternatives you've considered
I believe that the best option would be to insert this on the edit contact information page.
It would be also helpful to be able to search the device for pictures, take one on the spot with the mobile camera and also crop the image to better fit the profile.
