Test for ABSPATH in all files?

[n9yty]

I had come to believe that it was good practice to test if ABSPATH was defined in all the PHP files of a plugin, and I see you only test for it in the main top-level file.

I don't know if this is an issue or not, but raising this for at least consideration.
