[dev] Import/Export patches

[Chuck Hagenbuch]

Quoting Jan Schneider <janmailing@gmx.de>:

> You both convinced me, but I made two changes:
> 1) Export is disabled by default for the public directories.
> 2) I let the import/export feature be disabled for each application 
> individually.

Both sound good.
