policy: Lower default relay fee to 0.0001/kB. 
This lowers the default minimum relay fee to 0.0001 DCR/Kb from its
previous value of 0.001 DCR/Kb and increases the high fee multiplier to
keep the same default high fee threshold of 1 DCR/kB.

In order to keep the comments accurate, it also updates the comments in
the isDust function and the sample config file to match the new default
relay fee as it's nice to have the most recent values as a reference in
the comments.

Finally, it updates the tests for the expected new values as a result of
the reduced default relay fee and adds add a couple of dust tests just
below and above the dust point for the new reduced default relay fee.

It should be noted that this is only a default node policy change and as
such does not affect the consensus rules in any way.

; ******************************************************************************
; Summary of 'addpeer' versus 'connect'.
;
; Only one of the following two options, 'addpeer' and 'connect', may be
; specified. Both allow you to specify peers that you want to stay connected
; with, but the behavior is slightly different. By default, dcrd will query DNS
; to find peers to connect to, so unless you have a specific reason such as
; those described below, you probably won't need to modify anything here.
;
; 'addpeer' does not prevent connections to other peers discovered from
; the peers you are connected to and also lets the remote peers know you are
; available so they can notify other peers they can to connect to you. This
; option might be useful if you are having problems finding a node for some
; reason (perhaps due to a firewall).
;
; 'connect', on the other hand, will ONLY connect to the specified peers and
; no others. It also disables listening (unless you explicitly set listen
; addresses via the 'listen' option) and DNS seeding, so you will not be
; advertised as an available peer to the peers you connect to and won't accept
; connections from any other peers. So, the 'connect' option effectively allows
; you to only connect to "trusted" peers.
