.py4web_ignore issue and fix

[Tom Clerckx]

I had an issue with .py4web_ignore:

I had a sub-directory in my application directory that was not accessible by my user. Therefore I had put it in my .py4web_ignore file, but this caused an error during the processing of the files/directories by the dashboard.

Fix in the dashboard application:
