Update: Finalizing StringView
- StringView's constructor now follow's Span form (source, start, len) instead of (source, start, end). Fixed updated unit tests.
- Reimplemented CompareIgnoreCase via EqualityComparer<T> instead of IEqualityComparer<T> as per MS recommendation.
- Annotated every public method with xml docs
Test: ran unit tests - all green. Checked ServerBrowser - still good.
