DRY up protobuf declarations and move to a slightly briefer naming
convention.
Also dropped some ArrayBuffer -> string conversions as
ProtoBuf.js handles ArrayBuffers just fine, and in fact, more
efficiently than strings.
Finally, dropped the btoa() wrappers, because that incurs an extra
string -> string conversion before the protobuf's internal string ->
array buffer conversion. In lieu of btoa, we can simply pass in the
optional string encoding argument to the protobuf's decode method,
which in these cases should be 'binary'.

ERHMAGERRRD testing frameworks are so the best. Removed all our custom
code for ensuring test exclusivity and doneness and isolating callbacks
and everything. mocha does it all for us, and makes it pretty.
Also rather than return a long chain of promises that eventually resolve
to truthiness, we now use chai to make assertions about what is good and
right in the world.
