New Pyxie Release 0.0.16

Summary: Adds initial Arduino LEONARDO support, improved function call, release build scripts

In particular, to compile for a compilation target you do this:

pyxie --profile arduino some_program.pyxie

This will generate some_program.hex. You then need to load this onto your
arduino. Support for assisting with this will probably be in a largert
version. Requires Arduino.mk to be installed in a standard place. Docs TBD
as functionality stabilises.

Features

• Arduino LEONARDO compatible compilation profile (#3)
  • Detect that we are in a profile mode from a command line switch (#3.1)
  • Code generation is called with current profile (#3.2)
  • Code generation outputs code targetting "setup" instead of "main" (#3.3)
  • Makefile uses the arduino makefile #arduino leonardo (#3.4)
• Compilation profiles support removal of elements of the clib (#4.1)
• Function calls that do not require arguments work (#2)
