Remove unnecessary features

[k4kfh]

Much of the project has become a conglomerated mess. I tried to implement too many features at once, and it became awful spaghetti code that did a lot of little things and didn't accomplish the main goal.

There are several unnecessary features, especially with the air system, that can be removed to decrease maintenance headache. These include:

• Horn/Bell flow rate tracking; it's negligible [DONE]
• Remove the redundant air portion of the realtime object [DONE]
• Change prototype to proto to prevent obnoxiously long variable names [LONG TERM]
• Change coefficientOf to coeff for succinctness [DONE]
• Remove lineLength variable from the brakes since we can just specify propagation time instead in latency [DONE]

In the most recent commit for these efforts, I made the following changes to the temporary template file. I will implement the minor code changes in the physics engine for these changes later this evening.

• Moved .prototype.realtime.air.compressor.calc() to .prototype.air.compressor.calcFlow()
• Moved .prototype.realtime.air.reservoir.main into prototype.air.reservoir.main
• Removed .prototype.realtime.air.reservoir.main.dump because I am removing that feature
• Removed lineLength from brake object since it is redundant
• Changed .prototype.air.compressor.flowrate to .prototype.air.compressor.flowrateCoeff to better describe it
• Removed .prototype.realtime.fuel and added .prototype.fuel.status to make up for it
• Removed .prototype.realtime.grade since it's not implemented and isn't feasible to implement without RAILCOM hardware
• Changed .prototype.coefficientOf to .prototype.coeff for simplicity
• Removed .prototype.type redundant variable
