Put findings on a directory

[ciera]

AndroidLint can produce a directory-level note. Right now, shipshape is filtering out that note because it has a path that is not one of the files it is working on.

We probably should modify this to allow notes on a directory if that directory had analyzed files.

When this is fixed, change the end_to_end.sh script. The correct number of android lint tests is actually 9, since one was on a directory.
