core/types, core/vm: improve docs, add JSON marshaling methods In this commit, core/types's types learn how to encode and decode themselves as JSON. The encoding is very similar to what the RPC API uses. The RPC API is missing some output fields (e.g. transaction signature values) which will be added to the API in a later commit. Some fields that the API generates are ignored by the decoder methods here.

core, core/vm, eth/filters: move Removed field into vm.Log This field used to be assigned by the filter system and returned through the RPC API. Now that we have a Go client that uses the underlying type, the field needs to move. It is now assigned to true when the RemovedLogs event is generated so the filter system doesn't need to care about the field at all. While here, remove the log list from ChainSideEvent. There are no users of this field right now and any potential users could subscribe to RemovedLogsEvent instead.
