"String" type item allows entry of new lines, but UI does not handle them

[williamito]

Describe the bug
The definition of the "String" type and the UI implemented for it strongly implies it should only be a single line of text, as the "Text" type exists for multi-line text. However, "String" accepts multi-line text input but does not accommodate it visually.

Component
SDC Library

To Reproduce
Steps to reproduce the behavior:

1. Open any Questionnaire with a "String" item
2. Type stuff and press "enter", then type more stuff

Expected behavior
Prevent entry of multi-line text, e.g. using android:inputType="text" (see https://stackoverflow.com/questions/31965330/disable-enter-in-edittext-android), or have the text box expand to accommodate it

Would you like to work on the issue?
I think I can do this if it's just editing variables in the layout file
