Title: Fix #118, Only check K projects for XML documentation errors

- ignore leftover XML files e.g. from other branches
- tested manually in MVC repo with a bad doc file outside a K project
- align with clean target: that only removes bin directories under K projects
- approach ignores XML files in .csproj projects but no such projects in
repos where _k-xml-docs-test.shade file is used
