Bob Nystrom d4acbe8a70 A vertical slice of real libuv integration.
This adds a "timer" module to the CLI that provides a Timer class with
a static sleep() method. Not the most exciting functionality in the
world, but it requires the full hunk of libuv integration:

- The CLI sets up libuv and runs the event loop.
- Added a new directory src/module for CLI modules.
- Updated all the make scripts to handle it.
- Reorganized some other CLI code.

Makefile

# Makefile for building a single configuration of Wren. It allows the
# following variables to be passed to it:
#
# MODE - The build mode, "debug" or "release".
# If omitted, defaults to "release".
# LANG - The language, "c" or "cpp".
# If omitted, defaults to "c".
# ARCH - The processor architecture, "32", "64", or nothing, which indicates
# the compiler's default.
# If omitted, defaults to the compiler's default.
#
# It builds a static library, shared library, and command-line interpreter for
# the given configuration. Libraries are built to "lib", and the interpreter
# is built to "bin".
#
# The output file is initially "wren". If in debug mode, "d" is appended to it.
# If the language is "cpp", then "-cpp" is appended to that. If the
# architecture is not the default then "-32" or "-64" is appended to that.
# Then, for the libraries, the correct extension is added.
# Files.
