09cb5f2 added a %send-point call, which is meant to target the delegated sending
contract. For %invites batches, this was the case. Handling of %single, however,
still sent all calls to the ecliptic contract.
This looks at the call tag to determine the target contract.
For generating many sendPoint() transactions for the Delegated Sending
contract. Specify what ship to send the invites as, and a path to a file
containing lines of "~ship,~ticket,0xaddress".
Comes with a generator, |claz-invites, for generating such files, given
a star and a range of its children (and an output path).
