+	* providers/imap/camel-imap-folder.c (imap_get_summary): Started to implement
+	(imap_summary_get_by_uid): Started to code, I've got to find a way to get the 
+	date in time_t format and also get the flags
+
+	* string-utils.c (strstrcase): Added this convenience function - I know about
+	strcasestr() but it's not portable.
