Fixes OpenVPN Connect crash on iOS 8 when non-OpenVPN VPNs are used.
Mainly based on a research made by saurik, which is mostly correct: https://www.reddit.com/r/jailbreak/comments/2k32z4/openvpn_users/clvo2sk Thank you very much, you eased my work a lot.
The source code is fairly ugly but it works for me (and was originally designed to work only for me). If you dislike it, feel free to make a pull request. I decided to release the tweak and its source because neither iOS 8.3 nor OpenVPN itself are fixing anything for some time already :/
You may grab the binary for your repos.
