MAPI, Railroad and Port Tweaks

**Updated for 1.8**

MRPT is a lightweight mod that adds common sense changes to MAPI, Railroads and Ports.

I was never happy with the way the MAPI mechanic was utilized in the game and tried a few mods to make it work but was never truly satisfied. Thus my modding adventure began.

What does this Mod Improve?
- Makes Railroads and Ports more impactful to the economy by adding adding MAPI bonuses with up to 5% each depending on PM.

- Changes which technologies that add MAPI bonuses to more sensible technologies. Road Maintenance decree now adds a small percentage of MAPI.

- Adds a small amount steel as an input good(how are you gonna have railroad tracks without steel?) and adjusts other inputs and outputs accordingly to keep the same profit margins.

- Makes railroads more profitable once you research steam trains and adds automation PMs so you no longer have to subsidize every railroad.

- Adds a slight AI weight to the new MAPI technologies so the AI takes advantage of MAPI bonuses which means better AI economies.


Change notes:
- Changes the base MAPI value from 75% to 70%
- Traditionalism penalty lowered from -15% to -10%
- Market capital adds +2.5%
- Road maintenance decree adds +2.5%
- Stock Exchange bonus reduced from +10% to +5%
- Combustion Engine adds +2.5%
- Central Planning adds +2.5%
- Macroeconomics adds +2.5%
- Paved Roads now add +5%
- Ports add +2% with anchorage, +3% with cargo ports, +4% with industrial ports and +5% with modern ports
- Railroads provide +1% with experimental trains, +3% with steam, +4% with electric and +5% with diesel
- Unincorporated states have a 5% penalty
- All Railroad techs now require an input of 2 steel.(With adjustments to other inputs and outputs based on PM to keep profit margins the same)
- Zeppelins provide +10% prestige instead
- Adds Railroad Gauge and Automation PM's to railroads increasing state infrastructure and transportation goods
- Added a slight AI weight to research railways, Port tech, and MAPI technologies
- Adjusted transportation outputs to make railroads more profitable
- Adds railroad automation PMs

- Max Land MAPI: 95% = 70 + 17.5-Tech + 5-trains + 2.5% RM Decree
- Max Coastal MAPI: 100% = 70 + 17.5-Tech + 5-Trains + 5-Port + 2.5% RM Decree
- Major Rivers and Market Capital can add another 5% and 2.5% respectively (MAPI is capped at 100%)



Special Thanks to the authors of Make my Railway Profitable Again and Railway Automatic Expansion Fixed for finding the scrap game files for gauge PMs and fixing the auto-expansion logic of railroads
