Outdated "LookAhead" Interior Camera 2.5

- fixed bug in camera rotation while standing still

- updated codebase to match newer game versions
- removed some not-used legacy code
- refactored "look back" logic to match behaviour of base game (more realistic)
- fixed "Hide in cockpit" function

Fixed bug which breaks the ui app.
The api has been changed minorly.

Fixed bug which breaks the game (again). Unfortunately my workaround from update 1.9.1 no longer works, because a reload of the camera module triggers an error. As a quick fix I removed the "fixModdedCamerasNotLoading"-app and added a new button to the camera settings app called "init cam".

Fixed bug which breaks the game

- switched from unsupported serialization functions to json coder functions
- removed old "lookAhead" camera

Refactored the code for ~20% performance increase. Added a deprecation warning to old camera.

Fixed settings were not saved. The settings now work on the fly.
Also added a look back function which works with the default binding.

Fixed an error with a nil value calculation. Added the functionality to disable ui-apps via the native "Hide in cockpit" checkbox. Also fixed a typo in a debug message. The settings app also features a checkbox to disable the reverse look feature.

The camera script gets loaded from the core_camera module, but apparently the core_modloader is loading the mod after the core_camera modules was initialised and thats to late. I build a workaround with a UI app. In order to work you must add the "fixModdedCamerasNotLoading"-app to your UI. The app can also be uses by other developers. It simply triggers a reinitilisation of the core_camera module.
