`Launch Control` activation/deactivation from Lua script

[kifir23917]

We need to have a possibility of activation/deactivation Launch Control from Lua script. To implement this functionality we need to:

1. register new Lua function setLaunchControlActivated that accepts a single boolean parameter
2. add a new option Lua to the [Activation Mode] drop-down list on Launch Control dialog in TunerStudio:

When Activation Mode is Lua, ALL the following conditions should be satisfied to make an engine working in PreLaunch/Launch modes:

• switch condition: true was passed as parameter to the latest setLaunchControlActivated fuction call
• speed condition: Vechicle Speed is less than [Speed Threshold (kph)] setting
• TPS condition: TPS is greater than [TPS Threshold] setting
• RPM condition: RPM is between [Launch RPM(rpm)] - [Launch Control Window(RPM))] and [Launch RPM(rpm)] (for PreLaunch mode) OR RPM is greater than [Launch RPM(rpm)] setting (for Launch Mode)
