Nodes can now be implemented by arbitary C# methods. Graph structure is specified through expression trees implemented using Bg* types, which are not substituted with values until execution time. Doing so allows determination of node and option dependencies for a particular target, allowing us to generate dynamic UI for presenting relevant settings to the user.
Includes partial implementation of Installed Build script as an example implementation.

Defer resolution of the Project path until Execution time. This allows for build graphs to refer to projects that may be missing on the workspace, and still execute valid nodes in the graph.

* UE4Build was deleting all files in the manifest before running, even if they were output by UBT.
* Lumin was specifying AllowParallelExecutor="false" in InstalledEngineBuild.xml, which was causing each compile to be executed in isolation. Since modules are now compiled into object files separately to being linked into binaries, this was causing object files and .precompiled files to be deleted during the clean operation.
* Individual compile tasks can now override the global "clean' option.
