Fixed issue with sandbox options not using the updated custom values.

Updated sandbox options to have a maximum of 100 (was 5)
Added compatibility code for the Simple Ovehaul Traits and Occupationsl. The SOTO mod code replaces some of the fuel timed actions, which causes the Pay and Pump code to not run. This update replicates the SOTO code effects while still allowing the Pay and Pump code to run.

Fixed missing code so it uses the propane price.

By popular demand I have added support for:
-- Pumps Have Propane https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2739570406
-- CreditCardsPlus https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2873621032
-- Snake's Mod https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2719327441 (PremiumCreditCard)

Note I have not released the Pumps Have Propane : Fill Large Propane Tank because I can't find one to test, and don't know where it comes from. If anyone knows the item Type and which mods includes it please let me know and I will be able to test and release sometime.

Updated fuelStation detection to use the name of the texture for gas2go and fossoil, instead of IsoThumpable so FuelAPI barrels are still free.

Updated to handle the FuelAPI take gas from barrel. The FuelAPI uses the same ISTakeFuel TimedAction for handling (ie: pretending the barrel is a fuelStation. This change checks if the fuelStation is an IsoThumpable (FuelAPI barrel) A vanilla fuelStation is an IsoObject.

Updated to work with Compatibility for Tread's Fuel Types Framework [41.65+].
Added price/litre for Petrol (default) Diesel and LPG.

Refactored the Take Fuel timed actions so the :start() function does not require overriding. I override the new() instead.
This avoids a fault which occurs if the "Simple Overhaul: Traits and Occupations" mod is in-use.
Happily enough, this update removed some code I was uncomfortable to have, as it was a copy/paste of the vanilla code, and I really, really don't like doing that.
