See Bug 23473 - CalendarCompose: Find Attendees downloads entire GAL

Just checking that there isn't already some supported way for these dialogs to default to opening personal address book rather than listing the entire GAL.

As it stands, we need to tell users to avoid those functions, because they are unusable with an external-LDAP-defined GAL of nontrivial size.

Also seeking the wisdom of the community for the "right" fix to this problem. Paged results from the GAL? Make it so that you can limit # of results returned from GAL lookups while still allowing Outlook to download the whole thing?
