Feature: Enhanced CMake Build Script

[guestnone]

This extends and refactors the original CMake script to make it nicer. The structure of it is loosely based on that used in bs::framework project.

• Separate the Main SDK build definitions to its own CMakeLists.txt. Source file lists for each project were also moved to file CMakeSources.cmake, cataloged based on a folder they're in and the filter definitions for VS were added.
• During build the executable/library artifacts are now stored in <BUILD_DIR>/<BIN_OR_LIB>/<ARCHITECTURE>/<BUILD_TYPE>. The scripts were modified to reflect that change.
• Added most of the build flags from the original VS project with some new ones.
• Added some properties to explicitly configure the build environment.
• Add ability to install the libraries for distribution.
• Other small renaming, cleanups and things that I've forgotten.

Sorry for the delay, friends. I've been super tanked at work! LGTM.
