* BUG: Enumarting something inside a _next() enumerator method now is safe. [GB.SETTINGS] * NEW: Settings.Keys is a new property that enumerates keys stored in a settings file. This property can be used like an array if you want to enumerate keys under a specific slot only. git-svn-id: svn://localhost/gambas/trunk@1682 867c0c6c-44f3-4631-809d-bfa615b0a4ec
