[Feature Request] Group all not found errors while globbing

[bendtherules]

What happens now :

Running this command using sl * on a directory which contains multiple project directories (some of which are not node projects) shows console output like this:

   asp-project-1
   No package.json file found: C:\Projects\asp-project-1


   python-project-2
   No package.json file found: C:\Projects\python-project-2


   somefile.zip
   Path needs to be a directory: C:\Projects\somefile.zip


   node-project-1
    - test : echo "Error: no test specified" && exit 1

Expectation:

Instead of mixing (in terms of line-wise console output) the node project folders with other files and folders, group the not found files and non-node project folders and show them in the end.

Something like this:

   node-project-1
    - test : echo "Error: no test specified" && exit 1

   Ignored files and folder
   ------------------------
   asp-project-1
   No package.json file found: C:\Projects\asp-project-1


   python-project-2
   No package.json file found: C:\Projects\python-project-2


   somefile.zip
   Path needs to be a directory: C:\Projects\somefile.zip

You might also show the ignored section in some other way, like just printing out the files/folders name without detailed error reason for each of them.

Also, you might introduce a new flag to show the output in this way (like sl * --ignore), keeping the default output as it is. But atleast someway to have this kind of output will be nice.
