IncludeFileSystem -> DefaultFileSystem (#677)

Improvements in 'singleton'ness of DefaultFileSystem
Made WrapFileSystem a stand alone type - to remove 'odd' aspects of deriving from DefaultFileSystem (such as inheriting getSingleton method/fixing ref counting)
Simplified CompileRequest::loadFile - becauce fileSystemExt is always available.

-/* Wraps an ISlangFileSystem, and provides the extra methods required to make a ISlangFileSystemExt 
-interface, deferring to the contained file system to do reading. 
-
-NOTE! That this behavior is the same as previously in that.... 
-1) getRelativePath, just returns the path as processed by the Path:: methods 
-2) getCanonicalPath, just returns the input path as the 'canonical' path. This will be wrong with a file multiply referenced through paths with .. and or . but 
-doing it this way means it works as before and requires no new functions.
