X11: Minor changes in windowRaise()
Omit QAbstractItemView::dataChanged()

Parameters of QAbstractItemView::dataChanged() have changed in Qt 5.

Incorrect (not overriding virtual method as it should) method was just
silently ignored. This is why "override" keyword (C++11) is needed.

Update ignore rules for the copyqcon project
copyq.com: Do not use "args" to get the current executable name

When just typing "copyq", "copyq.com" gets executed but args[0] also
just contains "copyq" without the ".com" extension, triggering the
"Unexpected binary" error. Fix this by using applicationFilePath().
copyq.com: Do not pass the original args[0] when executing copyq.exe

args[0] contains the path to "copyq(.com)" and no arguments yet.
