[logback-user] Exception and error safe logging

[Ceki Gülcü]

Checking up on this, the AppenderBase and UnsynchronizedAppenderBase 
classes catch all instances java.lang.Exception and derivatives but not 
java.land.Error.

At present time, you would need to handle OutOfMemoryError on your own.

Sorry for the bs in my previous message.
