Work on Field Host Profile

Not yet ready....

@laspluviosillas  - I'm working on the d&d for the Login profile. Are you able to help guide me as to what is missing? I'm a little lost by the JS.

I think the second function isn't needed unless I have the delete image ability, so, that might go...

This line `= render @login.profile_picture` gives me an error. My `profile_picture is blank so ultimately this translates to `= render ''`, which fails because basically you're telling rails to render a partial named '' which is not a valid partial name.

What is the intention behind this line?
