Cleaned up some typos and JSDocs in Transactions

Nonce tracker is not fully documented yet.
Have not yet touched:
- tx-state-manager
- tx-state-history-helper
- util

 A txMeta is the "meta" object it has all the random bits of info we need about a transaction on it. txParams are sacred every thing on txParams gets signed so it must
 be a valid key and be hex prefixed except for the network number. Extra stuff must go on the txMeta!
