This will ensure that the latest version of test that claims to support
args 0.12.0 will actually run correctly with that version. After this is
released, I'll re-add the separators and fix the args constraint.

This adds an event that prints the total number of suites that will be
loaded, and includes the number of tests to be run in each group. This
enables a monotonic (if not entirely accurate) progress bar.

Previously we were running the tearDown in parallel with the next test,
which caused some pretty bad bugs.

When the browser is paused at a breakpoint, the runner will now open a
command-line console with a "restart" command that will restart the
current test.

This currently has no tests, due to dart-lang/sdk#25369 and the lack of
a programmatic API for interacting with Observatory. I've tested it
reasonably thoroughly by hand, but it's more likely than the average
feature to have lurking bugs.

See dart-lang/http_multi_server#1.

I'm choosing not to add a section to the README until the feature is
complete. I don't want to encourage people to use tags for long-term
testing until we support a configuration that can include the set of
valid tags.

When a group was skipped, it was being filtered out entirely since it
had no tests. This preserves it so that it can print a skip message.

This is specifically to allow Sky to get sky_shell support into the test
runner immediately. It's temporary; it'll last until we land proper

This was caused by us sending down a different suite ID when we created
a suite than when we got rid of it. There was *no* overlap between the
two IDs, so no test suite iframes were ever being removed.
