From Uses the homestead consensus rules to determine whether the signature is valid.
From caches the address, allowing it to be used regardless of Frontier / Homestead. however, the first time called it runs signature validations, so we need two versions. This makes it easier to ensure backwards compatibility of things like package rpc where eth_getblockbynumber uses tx.From() and needs to work for both txs before and after the first homestead block. Signatures valid in homestead are a subset of valid ones in Frontier)
