Ios gl3 and some improvements (#295)

* Added initialization of GLES30
Implemented native methods

* Forcing iOS java to be compiled using 1.8 bytecode because of java11 being the included sdk

* Fixed some typos

* Fix

* Implemented glTexParameterf and added source parameter to ant javac build

* More gl functions implemented

* Fixed typo

* Fix rendering issue in ios 13.0 ref: https://hub.jmonkeyengine.org/t/my-experience-with-jme-on-ios/31192/47

* Reverted last change, it didn't solve the issue with 13.0

* Fixed proguard settings

* Added Dummy.storyboard to be used as "Launch Screen File" to avoid bad aspect ratio and being able to use the whole screen and the proper resolution

* Fixed screen not starting properly on ios13.0 devices

* Changed fix for ios13.0 booting app not in full screen

* Removed useless comment
