Title: Added `target` option on :simulator task

To specify which version of simulator starts,

```
$ rake target=4.3 # => simulator starts with iOS 4.3
$ rake target=5.1 # => iOS 5.1
```

If `target` is not specified, `deployment_target` is used by default.
(Is `sdk_version` preferred?)

----
If we want to support multiple OSs we need all of BridgeSupport files for them, is it right?
86d39de1 is dealing with this case.
