Added trans state and removed watch address etc

Browse Source 
The transient state can be used to test out changes before committing
them to the proc state. The transient state is currently being used by
the gui to support proper nonce updating without having to wait for a
block. This used to be done by a cached state mechanism which can now
safely by removed.
