[web2py] Pack applications stored on control version filesystems

[José L .]

Hi
I was having problems (Internal error) when trying to pack an application 
that I have under subversion control.
I've detected the problem was in the app_cleanup function in gluon/admin.py 
(it tried to remove files, but raised an error when tried to remove the .svn 
directory).
I guess this will happen with any control version system that creates this 
kind of hidden directory.

Attached is a very simple patch that solved the problem for me.

Regards.
