Added DXF R2000 vector logo.
Change dfu.py to be Python 2/3 compatible

* Chane dfu.py to use Python 3 syntax to avoid dependency on Python 2.
* Update Makefile to call python instead of python2
* Fix #33
Basic implementation of import.

import works for simple cases.  Still work to do on finding the right
script, and setting globals/locals correctly when running an imported
function.
Add note about implementing inplace operators.
Change mp_compile so that it returns a function object for the module.

Merge pull request #43 from chipaca/master

Implement list addition.
m_realloc: Account only allocation size difference in total_bytes_allocated.
Add new alloc metric: current_bytes_allocated.

Unlike total_bytes_allocated, this tracks m_free()'s too.
Add new alloc metric: peak_bytes_allocated.

This is just max value of current_bytes_allocated seen.
Make it possible to turn off collecting memory stats (MICROPY_MEM_STATS).
Rename default config file to mpconfig.h, and port's to mpconfigport.h.

mpconfig.h will automatically pull mpconfigport.h.
