add static link library target

hi, I added SLL target to the workspace.

This configuration contains a lot of configurations as follows:

- `libJavaScriptBridge`, which is SSL for iOS, has been added.
-  `Tests` scheme has been deleted.
- `JavaScriptBride` target has been renamed into `JavaScriptBridgeApp`
- `JavaScriptBridgeTests` has been linked with `JavaScriptBridgeApp` and `libJavaScriptBridge` as a primary test target.
- removed almost all of `compilied source` for `JavaScriptBridge` in `Build Phases`, because of adding dependency of `libJavaScriptBridge` to it.
- `.travis.yml` also has been changed.

I have tested all targets in workspace in local environment, with success.
So, Please consider to merge this pull-request for external use this repository.

thank you :)
