Add tests for triple click text selection in TextEdit.

Includes a minor behavioural fix for selectedText and getText so that
they return plain text strings for plain text content rather than the
raw text from QTextDocument which substitutes line break characters
with unicode line or paragraph separator character.  Rich text
documents still return the unicode characters.
