plug-ins/print/Makefile.am added new files with utility functions. 

2008-02-25  Sven Neumann  <sven@gimp.org>

	* plug-ins/print/Makefile.am
	* plug-ins/print/print-utils.[ch]: added new files with utility
	functions.

	* plug-ins/print/print-settings.c: use the new utility
	functions for loading and saving GKeyFile.

	* plug-ins/print/print-page-setup.[ch]
	* plug-ins/print/print.c: also store the page setup in an image
	parasite. Fixes most of what remained to be done for bug 
#513291.
