Christopher Goes ad121f1498 Add a flag to export for zero-height start (#2827) ... Closes #2812 This PR adds the flag --for-zero-height to gaiad export, which runs several alterations to the application state to prepare for restarting a new chain in a consistent fashion. It also: * Moves Gaia's export code to cmd/gaia/app/export.go for cleaner separation. * Fixes an inconsistency where we treated the initChainer as happening at height -1 - it should now happen at height 0, since the first header sent by Tendermint has height 1. * Runs the runtime invariant checks on start (in initChainer) * Adds a few auxiliary functions to clear slashing periods * Removes the Height field from Delegation objects in x/stake, which was not used anywhere		2018-11-26 04:21:23 -08:00
