* Update Tendermint to v0.22.2
* Default ports changed from 466xx to 266xx
* Amino JSON uses type names instead of prefix bytes
* ED25519 addresses are the first 20-bytes of the SHA256 of the raw 32-byte
pubkey (Instead of RIPEMD160)
* go-crypto, abci, tmlibs have been merged into Tendermint
* The keys sub-module is now in the SDK
* Various other fixes
* [auth] Signers of a transaction now only sign over their own account and sequence number
* [auth] Removed MsgChangePubKey
* [auth] Removed SetPubKey from account mapper
* [auth] AltBytes renamed to Memo, now a string, max 100 characters, costs a bit of gas

* [keys] Keybase and Ledger support from go-crypto merged into the SDK in the `crypto` folder
* [cli] Rearranged commands under subcommands
* [x/slashing] Update slashing for unbonding period

to an infraction, slash them proportional to their stake at the time
* Add REST endpoint to unrevoke a validator previously revoked for downtime
* Add REST endpoint to retrieve liveness signing information for a validator
* [x/stake] Remove Tick and add EndBlocker

* [x/stake] Introduce concept of unbonding for delegations and validators
* `gaiacli stake unbond` replaced with `gaiacli stake begin-unbonding`

- You can now use a Ledger with `gaiacli --ledger` for all key-related commands
- Ledger keys can be named and tracked locally in the key DB
* [gaiacli] You can now attach a simple text-only memo to any transaction, with the `--memo` flag
* [gaiacli] added the following flags for commands that post transactions to the chain:
* async -- send the tx without waiting for a tendermint response
* json -- return the output in json format for increased readability
* print-response -- return the tx response. (includes fields like gas cost)
* [lcd] Queried TXs now include the tx hash to identify each tx

* [keys] New keys now have 24 word recovery keys, for heightened security
IMPROVEMENTS
* [x/bank] Now uses go-wire codec instead of 'encoding/json'

* revised use of endblock and beginblock
* [stake] module reorganized to include `types` and `keeper` package
* [stake] keeper always loads the store (instead passing around which doesn't really boost efficiency)

than some unintelligable panic

* a few other random ones...
* enhanced relay subcommand

BREAKING CHANGES:
* Remove `--data` flag and use `BCHOME` to set the home directory (defaults to `~/.basecoin`)
* Remove `--in-proc` flag and start Tendermint in-process by default (expect Tendermint files in $BCHOME/tendermint).
To start just the ABCI app/server, use `basecoin start --without-tendermint`.
* Consolidate genesis files so the Basecoin genesis is an object under `app_options` in Tendermint genesis. For instance:
```
{
"app_hash": "",
"chain_id": "foo_bar_chain",
"genesis_time": "0001-01-01T00:00:00.000Z",
"validators": [
{
"amount": 10,
"name": "",
"pub_key": [
1,
"7B90EA87E7DC0C7145C8C48C08992BE271C7234134343E8A8E8008E617DE7B30"
]
}
],
"app_options": {
"accounts": [{
"pub_key": {
"type": "ed25519",
"data": "6880db93598e283a67c4d88fc67a8858aa2de70f713fe94a5109e29c137100c2"
},
"coins": [
{
"denom": "blank",
"amount": 12345
},
{
"denom": "ETH",
"amount": 654321
}
]
}],
"plugin_options": ["plugin1/key1", "value1", "plugin1/key2", "value2"]
}
}
```
Note the array of key-value pairs is now under `app_options.plugin_options` while the `app_options` themselves are well formed.
We also changed `chainID` to `chain_id` and consolidated to have just one of them.
