[3] As a user I want to edit feed and feed provider uncomplicated to lose no changes

When editing a feed (provider) name, there should be no save button. Everything should be saved when clicking back. Text fields gain a "x" button on edit, allowing to reset the text field to whatever the name is now (See each bar).

ToDo

Custom:

• Add "x" button in texfield on edit
• Remove "Save" button and save on "Back"

Defaults:

• Report Changes in UML
• Report Changes in Wireframes

Acceptance criteria

Custom:

• Save Button is gone
• "x" appears on edit

Defaults:

• Naming Convention for Classes, Functions and Variables are met
• Comments are sufficient
