use DISTFILES instead of OTHER_FILES in docs, templates, and editors

the latter variable is entirely meaningless to qmake and should have
never been recognized by creator. unfortunately, qmake's dist target
wasn't very useful before qt 5.4, so it didn't occur to anybody to
actually use the variable associated with it, even though it is
semantically exactly the right thing.
