Fix broken links

Searched for lines matching `var \w+;`. This is a much weaker version of
no-implicit-dynamic. This catches a bunch of places where we otherwise
had dynamic calls and tightens up types a bit. Where we are relying on
being able to parse to multiple types and then throw a specific
excpetion or return null on bad types I added an explicit `dynamic`.

- Delete dartium and content shell platforms
- Delete tests related to dartium
- Remove references to these platforms in docs
- Stop installing dartium on Travis

Closes #742

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
docs into a doc/ directory. Further in-depth documentation of specific
pieces of the runner will go in doc/ as well.

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
shell and have it work.
