[logback-user] error log : one email per request

[Ceki Gulcu]

To recapipulate, ThresholdFilter filters out all events other than 
ERROR. Thus, it is expected that the outgoing emails contain only errors.

Here is your original specification:

* All the messages logged during one request handling are grouped into
one email, and the email is sent only when error occurs (i.e. at least 
one of log events is at level ERROR)

This specification can be fulfilled by removing or at least altering the 
ThresholdFilter in your configuration file.
