Loki Daemon Callbacks for Blockchain activity

The daemon has the ability to execute arbitrary commands upon receiving a block, reorganising and or the block rate changes by launching lokid with these flags which could make interop between the two more robust.
--block-notify arg Run a program for each new block, '%s'
will be replaced by the block hash
--reorg-notify arg Run a program for each reorg, '%s' will
be replaced by the split height, '%h'
will be replaced by the new blockchain
height, and '%n' will be replaced by
the number of new blocks in the new
chain
--block-rate-notify arg Run a program when the block rate
undergoes large fluctuations. This
might be a sign of large amounts of
hash rate going on and off the Loki
network, and thus be of potential
interest in predicting attacks. %t will
be replaced by the number of minutes
for the observation window, %b by the
number of blocks observed within that
window, and %e by the number of blocks
that was expected in that window. It is
suggested that this notification is
used to automatically increase the
number of confirmations required before
a payment is acted upon.
Might need to plan ahead to figure out how to make this usable for the storage server so figured I'd drop this pre-emptively.

These flags are a bit awkward to use. We could change lokid to make http request to the storage server notifying of a new block instead.
