Adds EndTime to BaseData
Adds Period to TradeBar
Now filling data forward on days missing files/data
Some performance enhancements
Removed sorted dictonary in DataStream/AlgorithmManager
We round down fill forward data in the data stream since if we were to perform this in the data feed we would continually produce data at the same time and it would all go into the algorithm at once.
Changed system to use Margin Models, removing leverage wherever possible allowing for dynamic margin models.
Created first portfolio fill model for FOREX which treats it as a currency swap through the cashbook instead of a tradable asset.
Updated the Securities/SecurityPortfolioManager to use cashbook value + holdings removing FOREX virtual positions.
Created a new benchmark system for comparing quantconnect builds.
