 * RSentryComponent records exceptions to sentry server.

 * RSentryComponent can be used with RSentryLog but only tracts exceptions
 * as Yii logger does not pass the exception to the logger but rather a string traceback
 * RSentryLog "error" logging is not that usefull as the traceback
 * does not contain veriables but only a string where this component allows you to use
 * the power of sentry for exceptions.
