Rename Ajax function

Hi all,

Great plugin, i found a little issue.
In skuautoffxf_all_settings.php row 108/109 the plugin registers a function ‘my_action_javascript’ but this name is often used by other plugins. Result is that activating the plugin ends up with an fatal error because the function is already registered.

I encountered this problem and solved it by renaming the function name.

Regards!
