Basics for persistent text box functionality

Text is saved in the JSON upon closing and loaded on startup if the
flag “rememberTextBoxContent” is true (default). Text seems to be
escaped automatically for export into the JSON. Tested with quote
characters only.

Missing the UI for controlling this feature, as discussed.
