	* app/file/file-save.[ch]: removed file_save() and renamed
	file_save_as() to file_save() which always requires "uri" and
	"file_proc" to be passed. This functions does no more file_proc by
	extension finding and stuff.

	* app/actions/file-commands.c (file_save_cmd_callback): only call
	file_save() if the image has both uri and save_proc, fall back to
	file_save_as_cmd_callback() otherwise.

	* app/dialogs/file-save-dialog.c: completely chopped and
	reconstructed. Added tons of checks for extension vs. save_proc
	consistency and ask the user if she really wants to save weird
	stuff. Added masive debugging output because I'm far from certain
	that everything is correct.
