Description:
Change view of dialogue Input Field
Now text of hint in dialogue Input Field looks, as text field. But text field for enter value is under this upper field. It can confuse users
I offer change this: (see mockup from attach)
1. Delete word "Edit"
2. Change type of field with hint text from text field to label
3. Add word "Hint" (optional)

Steps to Reproduce:
1. Create in Writer document field "Input field" (Ctrl+F2, type -> Input Field). In bottom of dialogue Fields there is text field "Reference". In this field can enter text of hint for user, that will work with document.
2. In document double click on your field
3. Opens dialogue Input Field, that has TWO text fields! But user can enter his value only in bottom field in dialogue. Upper text field has text of hint from field "Reference" (see 1) and it can't changes.
4. I offer to change this problem (see attach)

Actual Results:  
In dialogue Input Field there are TWO text fields. But user need ONE

Expected Results:
In dialogue Input Field there is ONE text field. Without confusion


Reproducible: Always

User Profile Reset: No
