Release Trixy 2.0.0b0pre

Rewrote all code, providing a completely new interface to Trixy. There is now
a clear separation between servers, inputs, processors, and outputs, allowing
for more obvious code structure and readability.

Additionally, the trixy.ssl code is now available. At present, only the
trixy.ssl.TrixySSLOutput is working. This should make it easier to interact
with remote sessions that use encryption while still allowing unencrypted
access to the data in Trixy.
