Summary:                    [patch] CLI to honor user's ~/.editrc file
Description: 
Asterisk CLI ignores command line keybinding file ~/.editrc. By default,
Home, End and Delete keys are not bound to meaningful commands. The
attached simple patch fixes that, in such a way that:

1. If the environment variable EDITRC is set, it is taken to point to an
alternative bindings file.
2. Otherwise, if HOME is set, the file is looked up in ${HOME}/.editrc

If exists, the file is processed by the editline library el_source()
function.

The following sample .editrc file binds Home and End to move to the
beginning and end of command line respectively, Delete to delete character
right, and C-left and C-right to move by word:

bind \\e[3~ ed-delete-next-char
bind \\e[1~ ed-move-to-beg
bind \\e[4~ ed-move-to-end
bind \\eOC  vi-next-space-word
bind \\eOD  vi-prev-space-word

Add some new editline bindings by default, and allow for user specified
configuration.

I excluded the part of this patch that used the HOME environment variable
since
the built-in editline library goes to great lengths to disallow that. 
Instead
only settings the EDITRC environment variable will use a user specified
file.

Also, the default environment variable use to determine the edit more is
AST_EDITMODE instead of AST_EDITOR (although the latter is still
supported).
