21af495b65 Move screenshot task chain in Browser
Currently, it's impossible to do screenshots in parallel.
This patch:
- makes all screenshot tasks sequential inside one browser
- starts activating target before taking screenshot
- adds a test to make sure it's possible to take screenshots across
  tabs
- starts waiting for a proper page closing after each test. This might
  finally solve the ECONNRESET issues in tests.

279cd4c9fb Remote Browser's remoteDebuggingPort option
This patch remove remoteDebuggingPort option. Instead, browser
is launched with '--remote-debugging-port=0' flag, letting browser
to pick any port. The puppeteer reads the port number from the
browser's stderr stream.

This change cuts average browser start time from 300ms to 250ms
on my machine. This happens since puppeteer doesn't have to probe
network once every 100ms, waiting for the remote debugging server to
instantiate.

Fixes #21.

aaefec7868 Fix Travis-Ci tests
It turned out that the tip-of-tree chromium fails to start on Travis
because of two reasons:
- inability to run LinuxSUIDSandbox
- libnss3 library version being too small

Both problems happen because of the outdated "trusty" distribution
which is used on travis.

This patch:
- reverts the previous patch 9e6f779. Instead of introducing such
  a weird "api", both phantom_shim/runner.js and test/test.js no
  explicitly pass '--no-sandbox' flag to the browser
- updates the libnss3 lib on travis
