Configurable Exception Raising for rollbar.log

[ArturMoczulski]

Fixes #448

Usage:

$enviroment = "test";

Rollbar::init(array(
  "access_token" => $this->getTestAccessToken(),
  "environment" => $environment,
  "raise_on_error" => $environment == "test"
));

try {
  throw new \Exception();
} catch(\Exception $ex) {
  Rollbar::log(Level::ERROR, $ex);
}

Above configuration will cause the exception to be reraised only in the test environment

LGTM

Side note: in the description example, Rollbar::log isn't using the $ex that's passed in. If this gets cut/pasted for a doc example, look out for that.

Thanks for pointing that out @waltjones fixed it

Once this is released, raise_on_error needs to get added to the doc
