Subject: [PATCH] Use KTextEdit when building against KF5

When building against Qt5 and WITH_KDE enabled, the input widget
now is a KTextEdit again, making use of features like spell check.

Note that we'll add support for a stand-alone Sonnet framework to have
spell checking without KDE integration later on.
