jfkirk dc964a7e7d MAINT: Removes the ability to reference a global TradingEnvironment
This commit removes the ability to reference a shared TradingEnvironment through the zipline.finance.trading module. In place, the classes that require a TradingEnvironment, or its child AssetFinder, contain their own references to those objects.

This commit also adds serialization utilities that allow for the pickling/unpickling of objects without unintentionally their TradingEnvironments or AssetFinders.

Dale Jung 7892a6943f RFT: Remove Position management from PerformancePeriod. This cuts down
on the number of per-tick update that occur since they were duplicated
per each PerformancePeriod. Also opens up the path to cythonizing the
entire object
