would be nice to create CoverateThresholdTask

[FaZend <team@…>]

Would be nice to have a task that will validate the code coverage database and return an error if any class or method or entire project's coverage is lower than the specified threshold, for example:

<coverage-threshold database="./reports/coverage.db" 
  perProject="50"
  perClass="60"
  perMethod="70" />

The task will stop building cycle if coverage is less than 50% for the entire project, or less than 60% for any class or less than 70% for any method.
