Material design of common edit screen fields

The normal edit screen fields, such as phone number and location,
have been updated to look like the new Material design mocks. I expect
this to be the largest CL needed to finish b/18004959.

Aspects of the Editor that haven't been touched in this CL
- readonly editor
- collapse nickname and phonetic name into StructuredNameEditorView. Then make
  sure the layout is correct
- photo editor
- Material insert/delete interpolators (maybe fast_out_slow_in)
- account header

Some complicated/weird parts of the CL:
-KindSectionView no longer displays an "Add details" button. Instead
 it always shows an additional empty row for each mimeType. The logic
 that handles this is mostly inside #updateEmptyEditors(). A lot of code
 could be deleted from RawContactEditorView because of this.
-LabeledEditorView's adapter displays TextView's inside Spinner. In order
 to make the TextViews look like EditTexts, I set the EditText's background
 (so the 9patch padding is used) and then later remove the background.
-Instead of keeping an expansion_view_container in every single field,
 I only kept it where it was needed. As a result, I needed to add
 null checks into the TextFieldsEditorView base class.
-I made an effort to reduce the depth of the view hierarchy and reduce
 the use of LinearLayout weights for performance reasons, when it was
 easy to do so
