Provide summary of how many files analyzed, have issues and ignored (due to .bidsignore)

Could be as simple as expanding the total number of files in Summary

instead of

        Summary:                     Available Tasks:                      Available Modalities: 
        14966 Files, 750.13GB        movie                                 MRI                   
        88 - Subjects                rest

get smth like (might need tuning to fit into table like form)

866 ignored you are bad !

roughly 6% of files ignored: I am sure we can top that!

ha ha -- it was a hypothetical case, I had no .bidsignore in this one. But I bet we can find even more grave abusers since some really brought it to the next level (no globs were harmed ;) ):
