QLineEdit and QComboBox tasks

[Albert Vaca]

Hello guys!

There are two tasks in Qt5 Epics [1] to implement replace-on-drop for
URLs on QLineEdit and QComboBox. This is currently present in
KLineEdit and KComboBox, because this behaviour is needed for
KUrlRequester (bug [2]).

We (aacid, apol and me) have been discussing about it and we think
that this behaviour should be implemented using installEventFilter()
on KUrlRequester. This way KUrlRequester could be implemented using a
standard QComboBox without need to patch Qt.

If you agree, I will close those two tasks for Qt and implement this
feature using installEventFilter() in KUrlRequester.
