Suggestion: Qt should support the following X11 keys: XF86X K_Copy, XF86XK_Cut, XF86XK_Paste

Some enhanced keyboards include keys such as cut copy and paste, for example SUN keyboards.

It would be helpful to have support for these keys in Qt, i.e. these keys should be added to qnamespace.h, qkeymapper_x11.cpp and qkeysequence.cpp.

qnamespace.h:
Key_Copy = 0x010000bd,
Key_Cut = 0x010000be,
Key_Paste = 0x010000bf,

qkeymapper_x11.cpp:
#define XF86XK_Copy 0x1008FF57
#define XF86XK_Cut 0x1008FF58
#define XF86XK_Paste 0x1008FF6D
...
XF86XK_Copy, Qt::Key_Copy,
XF86XK_Cut, Qt::Key_Cut,
XF86XK_Paste, Qt::Key_Paste,

qkeysequence.cpp:

{QKeySequence::Copy, 0, Qt::Key_Copy, QApplicationPrivate::KB_X11}

,

{QKeySequence::Paste, 0, Qt::Key_Paste, QApplicationPrivate::KB_X11}

,
{QKeySequence::Cut, 0, Qt::Key_Cut, QApplicationPrivate::KB_X11}};
