Subject: Feature/view path (#824)

* Use 'is' over 'as' where appropriate.

* dynamic_cast -> dynamicCast

* Replace 'dynamicCast' with 'as' where has no change in behavior/ambiguity.

* Replace dynamicCast with as where doesn't change behavior/non ambiguous.

* Keep a per view path to the file loaded - such that diagnostic messages always display the path to the requested file.

* Add simplifyPath to ISlangFileSystemExt
Simplify (if possible) paths that are set on SourceFile and SourcView - doing so makes reading paths simpler.

* Fix small typo.

* Improve documentation in source for getFileUniqueIdentity

* Fix override warning.
