Safe Rotate and Drain
This takes an account rotest owned by key
2993f795d133fa5d0fd877a641cabc8b28cd36147f666988cacbaa4379d1ff93, rotates it
to key dea647009295dc015ba6e6359b85bafe09d2ce935a03c3bf83f775442d539025, and
transfers the whole balance to another account croesus. The croesus account
pays the gas which makes it easy to drain the rotest account balance to
exactly zero. The transfer out of rotest happens after the key is rotated
which means that this transaction MUST be signed by the key you are rotating to
and is therefore "safe"...i.e. it is impossible to accidentally rotate to an
incorrect key and lose control of the rotest account.
Signing
This transaction must be signed by both the key that owns rotest at the
beginning and the key that owns rotest at the end.
