CocoMUD client

When typing code causing exceptions of any kind in the Python console, a traceback occurs. To test:

1. Open CocoMUD.
2. Select a world (with or without a character) and connect to it.
3. Open the Python console (menu bar, file, Python console).
4. Enter something that will create an error, like print(unknown).

Error output:

Traceback (most recent call last):
  File "C:\Python36-32\Lib\code.py", line 91, in runcode
    exec(code, self.locals)
  File "<console>", line 1, in <module>
NameError: name 'unknown' is not defined

During handling of the above exception, another exception occurred:

wx._core.wxAssertionError: C++ assertion "wxThread::IsMain()" failed at ..\..\src\msw\evtloop.cpp(182) in wxGUIEventLoop::Dispatch(): only the main thread can process Windows messages

The error should display in the Python console like a normal exception would in the Python interpreter. This might be due to wxPython's update.
