Subject: new function, taking code from func_contains to get string
 properties.

	* addressbook/backend/pas/pas-backend-file.c
	(get_e_card_prop): new function, taking code from func_contains to
	get string properties.
	(entry_compare): new function generic, taking strstr-like function
	as a parameter.
	(func_contains): rewrite function to use entry_compare.
	(is_helper): new helper function to map strcmp to a strstr-like
	function.
	(func_is): new function, implementing "is" for searches.
	(endswith_helper): new function.
	(func_endswith) new function, implementing "endswith" for searches.
	(beginswith_helper): new function.
	(func_beginswith): new function, implementing "beginswith" for searches.
