The attached patch fixes the following:
-konsole sends wrong esc-sequence for home/end in xterm mode,
 ^[[H & ^[[F instead of ^[OH and ^[OF, as listed in terminfo for xterm,
 and as xterm, gnome-terminal, rxvt and Eterm do.
-konsole sends wrong esc-sequence for home/end in linux-console mode,
 ^[[H & ^[[F instead of ^[[1~ and ^[[4~, as listed in terminfo, and
 the real linux-console does.
-konsole sends asc-II del for del in xterm mode which should be ~[[3~,
 as listed in terminfo, etc.

And adds the following:
-shift F1-F10 send F11-F20 for both xterm and linux-console (just like
 the linux-console, rxvt, xterm Eterm & gnome-terminal).

It doesn't fix:
-the numeric keypad not honering application keypad mode, unfortunatly
 QT doesn't tell the difference between keyoad keys and normal keys.
