Changed package name c.q.l.classic.filter to c.q.l.classic.turbo

Trying to remote the activeFileName/fileName dual information in logback configuration.
The current version works in some situations but not all, and does not passes all the tests.
Please use with caution if building logback from repository.

Changing the EvaluatorAction pattern from configuration/evaluator to */evaluator lets the user create evaluators to go in the context's eval map *and* evaluators inside filter elements.
Same for MatcherAction

- Loggers now go through filter attached to their parent (loggerContext) before 
  any decision.

  This slows down decision making a little, but is much more flexible.

- Context is no longer FilterAttachable. This change was necessary in order to allow
  LoggerContext to be ClassicFilterAttachable

Access now knows about Evaluators. Working on Filters

- improvements to tests

- corrected a hard to spot bug in AbstractEvaluatorFilter. It has methods like
  
  public int getOnMatch()
  public void setOnMatch(String)

  public int getOnMismatch()
  public void setOnMismatch(String)

The fact that the getter returned an int and the setter took a String has PropertySetter confused.
I removed the getOn*match methods which were not used anywhere.
