Misc updates the display system....

Misc updates the display system. * PNG base64 encoding is now done at the ZMQ level, not in the display formatter itself. * All formatters are documented as to the exact nature of their return value. PNGs are not base64 encoded, LaTeX must include $/$$, Javascript should not have the <script> tags, etc. * Updated the Circle display example in docs/examples/core. * Renamed the sympy printing extension to sympyprinting.py.
