BUS: [Rulekeepor] FLR and SLR

[Kerim Aydin]

The FLR and SLR are up to date (up to Proposal 8052, and including revision
for the recent CoE on the Treasuror Rule):

I'm not publishing them, because there is (or was) a message size-limit on 
BUS that was specifically removed in OFF for the purpose of ruleset
publication.  I don't want to add to any confusion in case the rulesets
bounce from BUS.
