added to the nsIMsgProtocolInfo interface defaultCopiesAndFoldersPrefsToServer,
which we use to see for a given server type, do the defaults live on the server
or not (where not would mean "Local Folders").
fix the getFoldersWithFlag method in the nsIMsgFolder interface so it
would be easier to use in JS.

js. fix#23313, don't allow user to delete "local folders" account.
fix#23413, implement delete account. further divorce "none" from "pop3"
(which will be useful once we get to movemail and other incoming mail server types)
r=alecf
protocol info to see if username is required and how to preflight
the pretty name. (news does it different than imap and pop.)
to help the insane clown posse, create a string bundle to be used
by the account wizard.
fix the bug that I just introduced where creating accounts
would fail at the very end, so the folder pane would fail to refresh.
