- by default look for a user.props in the msvc directory, which is more convenient
than the built-in way of looking for such file in the user's home directory
- make git ignore the file
You can now append a zipfile (containining uncomressed python sources)
to the micropython.hex file.
Use MEMZIP_DIR=directory when you call make, or set that in your
environment to include a different tree of source files.
Added sample /boot.py, /src/main.py, /test.py and /src/test.py files.
Added run command so that you can execute scripts from REPL (until import is implemented).
Added build directory to .gitignore
