Exports have a basic sense of maximum amount, lowering by 1% in value for every sale, raising in 0.1% every 2 ticks up to it's max
* Update exports.dm
* Adds consistent marginal cost function (with decreasing marginal returns) and its associated antiderivative for total cost
* Tweaks get_cost procs and other properties in accordance with the new cost function
* Removes undefined vars causing errors
* Tweaks crates cost property
* I hate MINERAL_MATERIAL_AMOUNT AKA minor snowflake refactor
* Fixes price elasticity comments
* Changes var kelasticity to k_elasticity for better readablity
