* Statestore is now one word, without camelcase, eveywhere. Previous
names included StateStore, state-store and state_store,
variously. The only exception is a couple of flags that have
'state_store', and can't be changed for compatibility reasons.
* File names are also changed to reflect the standard naming.
* Most comments are now 90 chars wide (from 80 before)
