This also makes CompilerPool more general, so it can be used by both
the node and the browser platforms.

This reverts commit 35f9d92a.

This doesn't fully support the JSON reporter yet.

See #50

This adds `spawnHybridUri()` and `spawnHybridCode()` methods that spawn
VM isolates even when called from the browser. It still needs some
additional work to close the isolates when the test ends by default.

See #109

Fixes #436.

This just loads a subset of the config that can be pased on the command line
from the configuration file. The command line takes precedence over the config.

This adds a table of contents to the README, and moves the JSON reporter

It turns out that comma is a shell-active character on Windows. This
makes it so that Windows users can copy-paste the invocation into their
