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
* Update slashing import/export
* More slashing.WriteGenesis
* Add test import/export to CI
* Store equality comparison.
* Fix validator bond intra-tx counter
* Set timeslices for unbonding validators

This is to facillitate ease of implementing #1406. (Tags for messages
could then be added dynamically)
Ultimately once we make the router support hiearchical routing, (#770)
we can then remove the name field and just the parse info for tags from that.
Until then, we can parse the tag name as
`fmt.Sprintf("%s %s", msg.Type(), msg.Name())`
