Fix WebGL once and for all

* Refactored the assetbundle building script (and added a temporary workaround because for some reason the filenames are now lowercase).

* Changed the style used for preprocessor directives.

* Fixed PlayFab, and as such cake race should now work.

* Refactored NetworkManager

* Fixed integer overflows in `TimeManager.ConvertDateTime2Seconds(DateTime)` and `Spine.AnimationState.Update(Single)`. This fixes the instant crashes on development builds.

* Fixed `AnimationCurve`s in levels by telling unity not to strip the `AnimationCurve` class using a `link.xml` file. This should fix crashes in levels such as Little Pig Adventure.

* Updated README.md
