Renaming ‎SimulatorPacket::MinAlertRPM, MaxAlertRPM, RevLimiterBlinkAlertActive

[theRTB]

While implementing a shift tone for GT7 I've double-checked some variables in the telemetry packet, and the naming on these is awkward compared to their function. It would avoid confusion to any developer trying to use these variables if they're named a little more appropriately.

The float MinAlertRPM at 0x88 appears to be a hidden variable set per car (and upgrades) that often matches the listed upshift RPM in the Transmission Settings, but not always. The 787B has it at 9000, while the settings put it at 9500. The automatic transmission shifts at the latter value. It appears to be a multiple of 100 regardless of upgrades (ECU, transmission, RPM-affecting engine upgrades).

The revbar starts at 85% of this AlertRPM and starts blinking at 99%. For the 787B this is a range of 7650 - 8910 RPM. At this point the boolean flag RevLimiterBlinkAlertActive goes to True. So that's not really a revlimiter thing, it's more of a blinky-get-attention thing.

MaxAlertRPM refers to the peak RPM on the (ingame) tach, rounded up to the nearest multiple of 2000 when above 6000. It has no relation to the revbar blinking at all.

So as far as renaming goes, maybe something like this? MinAlertRPM -> AlertRPM MaxAlertRPM -> TachMaxRPM RevLimiterBlinkAlertActive -> (Upshift)BlinkAlertActive
