ask for permission

[GoogleCodeExporter]

I'm not always sure whether I want an app to have internet access. It would be 
a nice feature to have a box which would make the app ask for permission.

Then when the app goes to access the internet, DroidWall throws up some 
permission granting window and the user decides whether or not to grant 
permission that time. Possibly add a "remember action" checkbox which would 
store the result for block/allow without needing to open DroidWall to change it.

Thank you for a great app!
