Remove "at " prefix from function name in stack frames.
Always add 'abs_path' key to stackframes and set 'in_app' = true, otherwise stack frames are ignored by sentry.
Reverse order of stack frames as required by the sentry documentation ("most recent call last").
Send class name also if full qualified name did not contain '::' string, e.g. with instances of Error class.
Send also client information as HTTP info to sentry server.
Send user information (id, name, email) if provided.
