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

Browse Source 
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).
