When multiple instances of the Raven client are created through the Raven.Client() call, each single instance must be install()ed before the captureException/captureMessage calls.

However, install()ing the newly created client also installs the uncaughtException handler, which is not always the desired behaviour.

Installing the uncaughtException handler shall either be optional when install()ing the client, or install() should be made optional when captureMessage/Exception are called.
