1.0.0-beta1 release.

Zcash v0.11.2.z9

This version fixes a network protocol bug that prevented many users from
connecting to the z8 test network. It also solidifies the consensus protocol; we
do not expect to make any other changes to the consensus protocol, except for
possible security fixes, until after 1.0.
