Move the CAPABILITY command here so we don't have to keep checking each

2000-06-27  Jeffrey Stedfast  <fejj@helixcode.com>

	* providers/imap/camel-imap-store.c (imap_connect): Move the
	CAPABILITY command here so we don't have to keep checking
	each time we open a folder.
	(camel_imap_command_extended): If we are doing an EXAMINE,
	don't bother doing a SELECT first.

	* providers/imap/camel-imap-folder.c (imap_init): Update so
	folder->has_search_capability depends on the parent IMAP store
	(since this is really dependant on the IMAP implementation and
	not the folder)
