		introduce per-account filtering rules. Each filtering rule can now be assigned
		to a specific account (by default it's "All"), works w/ POP3/IMAP. Take care
		when applying filtering rules manually, as all rules will apply - even the ones
		assigned to an account. This issue will be addressed soon.
