Rewrote to take a third argument (gboolean *selectable) so that we can

2000-09-13  Jeffrey Stedfast  <fejj@helixcode.com>

	* providers/imap/camel-imap-store.c (imap_folder_exists): Rewrote
	to take a third argument (gboolean *selectable) so that we can
	find out if the folder is selectable or not as we look to see if
	it exists. Also, don't use EXAMINE because that will not work on
	non-selectable folders, so use LIST instead.
	(get_folder): Check to see if the folder exists even vefore
	calling imap_create as this will save time. If the folder does
	exist, find out if it's selectable. Moved the call to refresh_info
	here.

	* providers/imap/camel-imap-folder.c (imap_get_uids): Check for a
	NULL summary.
	(camel_imap_folder_new): Don't call refresh_info here - call it in
	get_folder() because we don't know if this folder even exists on
	the server yet! And even if it does, we don't know if it can hold
	messages or not yet.
