Feature request: Write warning for the included header file along with the source file if applicable

[swasti16]

Description:
Currently, we are only displaying warning for the source file, even if the header file has warnings. It would be nice to display a warning for header files as well.

@danmar what is your view on this? When we started on the extension we intentionally made it so that issues from files other than the one the user is viewing were not shown (unless deemed critical)

implemented in v 1.0.9 (note: we will skip showing errors for included files in the case that the user is using a project file, as per Daniels request)
