I forgot to update one instance of "go-ethereum" in commit 3f047be5.

Conflicts:
	common/config.go

The code in config.go is unused. The main reason for removing it is to
get rid github.com/rakyll/goini in Godeps (it has no license).

Genesis release. Closes #1402

All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".

crypto/curve.go is not our code and has its own license. This commit
excludes it in update-license.go and removes our GPL header.

Decoding did not reject byte arrays of length one with a single element
b where 55 < b < 128. Such byte arrays must be rejected because
they must be encoded as the single byte b instead.

Added PutBlockReceipts; storing receipts by blocks. Eventually this will
require pruning during some cleanup cycle. During forks the receipts by
block are used to get the new canonical receipts and transactions.

This PR fixes #1473 by rewriting transactions and receipts from the point
of where the fork occured.

Implemented the --genesis flag thru which we can set a custom genesis
block, including the official Ethereum genesis block.
