Make rendering a bit prettier

Replaced logo with something nicer and more relevant. Updated HTML
output to use the templating system and include label headers in the
table.
Work on JSON-RPC client

JSON-RPC client is now basically functional, capable of making calls and
receiving results. Still need to handle conversion of types in the
result correctly, and enhance the API documentation (HTML version for
human display, etc.)
Enhanced API docs

API documentation now renders nicely in HTML with ReST conversion of
handler docstrings.
Add docutils as server dep

Required for docstring conversions in HTML API doc output.
