Gravity Perks - Advanced Save and Continue 1.0.18

Fixed issue where Advanced Save & Continue could conflict with GravityImport.

Added support for setting a default Save & Continue email address (requires snippet).
Added new filter gpasc_attach_inline_confirmation_message to allow changing how the inline Save & Continue confirmation is attached to the form markup. It is prepended by default.
Fixed an issue where form would reset to first page when displaying the Save & Continue confirmation inline.
Added null check to gaurd against a rare fatal error.

Fixed issue where disabling "Auto Save and Load" while "Hide Save and Continue Link" is still enabled would continue to cause the Save & Continue button to not be displayed contrary to the settings hierarchy.
