Filename inconsistency: Rename app.php to wp-app.php

[johnbillion]

I thought this had been discussed before, but I can't find anything when searching Trac.

The filename of the relatively new file app.php is inconsistent with most of the other WordPress files installed to the root (with the exception of the legacy xmlrpc.php) in that it isn't prefixed with wp-. I suggest it's renamed to wp-app.php for consistency. Note that no official release has been released with this file yet so backwards compatibility isn't an issue.

Think it was only discussed on the mailing list: [wp-hackers] File names in WP base folder

I wonder -- is there anything in the specs or anything that defines /app.php as where the APP interface should be? I couldn't find anything, and unless that's the case, I'm +1 for wp-app.php.

Alright, Matt okayed this. Moving.
