vt320: Fix broken home / end keys

According to vt320 terminfo (as well as screen and xterm, which
connectbot uses to identify itself by default)
khome=\E[1~ and kend=\E[4~

The vt320.java however used \E[H for khome and \E[F for kend.
But \E[H is used as a sequence to "move cursor to home", and not
as a key escape code and \E[F isn't mapped at all.

The FunctionKeyShift[15] = Find and FunctionKeyShift[16] = Select
which were mapped to \E[1~ and \E[4~ have been removed from vt320.java.
They have never been used anyways.
