Added shortcode and all images radio buttons to gallery view.
Radio buttons for shortcode and all images save to postmeta as well as
the text field for the gallery shortcode.

Need to work out the logic next of which check box is used and then how
to filter the usual gallery shortcode.
Added shortcode_atts_gallery filter that allows us to intercept the
gallery short code and maipulate it.

Need to work out how to properly parse out the shortcode value that a
user enters and add the id attributes to the regular gallery tag.

What if the user puts extra atts in the shortcode? Or do we only allow
ids and maybe they add other atts to the tag in thd body?
Logic to exclude the default imgages (attachments) for the gallery and
include the user defined images.
added some documentation
More desecriptive explantion on buttons for what is going to happen
cleaned up some comments
tightned up the XMLRPC_REQUEST
Removed filter since the favpersonal theme is dealing with the output.
Changed the description for which gallery to show the default gallery or
the user defined shortcode.
Changed the name of radio buttons to better reflect what they represent
Removed extra div tags and class to simplify styling of input field
remove tabindex completly
