Many thanks to those who ran test builds and sent crash reports!

Release Notes:

This release of Immersive Railroading is a special one! It is the first release to use a common codebase for every minecraft version. Internally, UniversalModCore allows the same code to run on ANY version of minecraft that it's been ported to. This means that adding features to Immersive Railroading are completely decoupled from the idiosyncrasies of each minecraft version and development can happen much faster and with less backporting issues.

New Additions:

* Added Track Exchanger Tool @FriedrichLP

* New sw1500 Textures from @WrongWeekend

* New wrench from @FriedrichLP and @Thelegend5550

* Resources to run IR reduced (render to 2d icons during init)

* New config UI (see keybindings)

* Track preview rendered in blueprint tool

Improvements:

* 2d icons (generated in 3d) now used by default! This drastically reduces GPU requirements for IR

* Texture loading system improved to unload textures not in view. This also drastically reduces requirements.

* Chuffing is now quieter when the throttle is set to 0

* Support larger # of components (smoke/wheels/pistons/etc...)

* Handcar now uses saturation

Bug fixes:

* Fixed inventory randomly eating items

* Fixed a few null pointer exceptions in the track system

* Fixed deep snow crashing the game
