Update tdata reference

* Groundwork for nanocom boosters

* The item use handler now has a switch for multiple item types (currently gumballs, and a stub for boosters)
* All item types are now checked for expiration, not just vehicles

* implement nanocom booster helpers, save and expiry

* implement authentic taro and fm modfication

* magic number and code refactor

* make sure only close by group members are counted

* add safe taro fm handling, rate command, race and mission booster logic

* add config option to disable authentic group scaling

* rename for consistency

* make rates percentages, fix chat message, add config options

* add config option to the ini file

* add index guard for hasBoost functions

* reorder config ini options

* add bank item expiry option

* fix trade oversight

 ## Usage
 
 ### Getting Started
 #### Method A: Installer (Easiest)
-1. Download the client installer by clicking [here](https://github.com/OpenFusionProject/OpenFusion/releases/download/1.5/OpenFusionClient-1.5-Installer.exe) - choose to run the file.
-2. After a few moments, the client should open: you will be given a choice between two public servers by default. Select the one you wish to play and click connect.

 ## Compiling 
 
-OpenFusion has one external dependency: SQLite. The oldest compatible version is `3.33.0`. You can install it on Windows using `vcpkg`, and on Unix/Linux using your distribution's package manager. For a more indepth guide on how to set up vcpkg, [read this guide on the wiki](https://github.com/OpenFusionProject/OpenFusion/wiki/Installing-SQLite-on-Windows-using-vcpkg).
