* Image picker work in progress
* Small fixes

* image picker's getPicture method is now retaining the javascript picker object (and objC one) until the end of execution of the callback.
* Camera roll picker implementation seems complete.
* Fixed EJTexture's initWithUIImage method for retina.
* Removed the image format and jpeg compression parameters, not used any more.
* Image picker related cosmetics
* imagePicker: fixed the automatic max texture size when app is in retina mode.
* The binding to the method isSourceTypeAvailable is now returning a JS boolean value.
