This also applies some style fixes and handles some old blink codes.

Thanks Egmont Koblinger <egmont@gmail.com>!

Thanks Roberto E. Vargas Caballero! You were committing this patch against the
wrong version of the FAQ, so I had to rewrite it.

- Shift + End : Delete until end of line.
    - Control + End : Delete until end of screen.

When  the End  key is  pressed  without any  modifier is  not generated  the
correct sequence for it  (going to the end of the  screen), because the size
of the  terminal is not known,  so it is  not possible write a  sequence for
this purpouse.

Insert key stands for a key which allows enter or leaves insert mode, so let
it generates the correct sequence to change between these modes:

   - Insert: Enter in insert mode.
   - Shift + Insert: Leave insert mode (replace mode).
   - Control + Insert: Insert a blank line.

Like Shift + Insert also paste text, if a user want this feature be full
functional he has to modify such shortcut.

Keypad will generate keycodes when keypad application mode is enabled. It
can cause problems with some programs like vi, which operates in such
mode.

This patch change by default don't generate the keycodes never, but this
behaviour can be changed using the combination Alt + NumLock.
