CakePHP 2.4 support

Probably not compatible with cake < 2.4

According to the cake 2.4 migration guide:
>Log engines do not need the suffix Log anymore in their setup configuration. So for the FileLog engine it suffices to define 'engine' => 'File' now. This unifies the way engines are named in configuration (see Cache engines for example). Note: If you have a Log engine like DatabaseLogger that does not follow the convention to use a suffix Log for your class name you have to adjust your class name to DatabaseLog. You should also avoid class names like SomeLogLog which include the suffix twice at the end.
