gateone.js:  Increased `GateOne.Base.dependencyTimeout` from 5 to 15 seconds.  When there's a lot of other JavaScript to load it can take a while (especially over a slow connection).
app_terminal.py:  Fixed a bug with the log entry that displays which Terminal plugins are active was missing pure Python plugins.
setup.py:  Added html5lib to the list of dependencies and changed the Tornado version to require 3.2.
core/server.py:  Updated to require Tornado version 3.2 (because of the new WebSocket exception change).
Other:  Updated a few copyright comments here and there.
