No way to capture exceptions without installing a global error handler

Raven.captureException() won’t work properly when Raven.install() has not been called beforehand; calling Raven.install() will install a global error handler (window.onerror). This is problematic if one wants to catch errors with a custom handler and pass them to Raven by hand, e.g. to lazy-load Raven as needed.

This is really important to us as well, +1

Closing this because Raven.captureException works without calling .install today.
