Tell users which files were not searchable

Two issues:
* I couldn't find my files
* False negative results

I couldn't find my files
------------------------------------------------
Report shows just the filename, not the path.  I didn't know what path the file was under. Now, the path prints once, then all the files underneath it.

False negative results
------------------------------------------------
I had a bunch of files, with TODO that didn't show up in the report.

found that those files, when queried through Sublime console were different:
    view.encoding()
    files that failed ===> u'UTF-16 LE with BOM'
    files that succeeded ===> u'Undefined'

I could save them as UTF-8 and they would showup.

This code tells the user what files were missed by this package.  I would have fixed the code, but honestly, I don't deal with encodings hardly at all.
