Removal of src/Core/Thread and related refactoring throughout the code-base.

This is the first step in a series of infrastrucutre overhauls to modernize Uintah. Though this all passes local RT (both CPU and GPU tests), I expect some fallout we haven't considered and will be standing by to deal with any issues. Once the dust settles, we will move to replacing Core/Malloc with jemalloc.

* We are now using the standard library for all multi-threading needs within the infrastructure, e.g. std::atomic, std::thread, std::mutex, etc.

* The Unified Scheduler is now the only multi-threaded scheduler, e.g. ThreadedMPIScheduler no longer exists (though the source will soon be placed into an attic).

* Threads spawned by the Unified Scheduler are detached by default (not joinable), allowing for easy, clean and independent execution. There are no longer ConditionVariables used to signal worker threads, just a simple enum for thread-state.

* What was Core/Thread/Time.* is now Core/Util/Time.* - a next step will be to migrate all internal timers, etc to use std::chrono.

* NOTE: Though much cleanup has occurred with this commit, there is still significant cleanup and formatting to be done. The scope of this commit neccessitates a more incremental approach.

Fix more c++11-related warnings.

1.) Fix forward declaration of SimulationTime declared as a struct but defined as a class

2.) match delete[] with new[] (should fix a small memory leak)
