Trireme 0.8.8

In addition to the fixes below, this release makes progress on support for Node.js 0.12. Both versions
0.10 and 0.12 are included in the "trireme" NPM package and in the default JAR. Users may now select
either version when starting the script.

Support for 0.12 is still experimental. Most modules work well, however the child_process module in general
is not complete and that hinders testing for some of the other modules.

Issue 87 Fix flow control for HTTP requests and responses that
use the HTTP adapter. This prevents OOMs when large messages are streamed using HTTP using the Netty
adapter, the servlet adapter, and on Apigee Edge.
Issue 96 Change the Buffer class to use much more code
from regular Node.js so that it is is more compatible.
Issue 126 Change the way that the class loader is set up
in the "trireme-support" module so that a custom class loader may be set up for the JAR files that
this module loads.
Issue 128 Fix the way that TLS/SSL ciphersuites are translated
from OpenSSL format to Java SSLEngine cipher suites. The new method is much more compatible with
OpenSSL and many more applications should work that depend on particular ciphers.

Also, some of the callbacks in the HTTP module were fixed in the HTTP adapter so that they work the same
way as they do without the adapter, such as the "close" and "finish" callbacks.

Sadly, Node.js 4.0 is out and much of the source code won't compile with the current version of Rhino
due to dependence on ES6 features. The Rhino project is making progress on ES6 support but it will take
some time. The Nashorn script engine in Java 8 cannot compile this code either due to a different
set of ES6 incompatibilities.
