Window level higher than normal

When displaying the Toast under status bar the windowLevel is set to `UIWindowLevelNormal`. However, this is not fully correct because this window is on top of the main application window. When using this library with others like `SVProgressHUD`, they have problems identifying the proper place to insert themselves. Just adding a small amount (+1) works and configures this window on proper level (above the app).

Don't ask travis to update xctool anymore

Travis have upgraded to the latest xctool. Running `brew upgrade xctool` has a failure exit status if it is up to date (handy!). So let's err on the side of upgrade xctool when we start having problems with xctool.
Support for Rubymotion

The NSDictionary that rubymotion creates from hashes doesn't seem to gel well with `indexOfObjectIdenticalTo`, perhaps something to do with the way constants are handled? This change allows CRToast to be used with rubymotion while keeping the valid key checking intact.
