aero: enable misc settings for defy

Previously this was a one way road. Either the
device was a defy and had its own fragment or
it used the misc fragment.
Since the misc fragment has now a new feature
called 'Your Settings', Defy users should
benefit from it the same way.

profiles: add impoer/export of profiles

Users have now the option to either import exisiting
profiles (if available) during the "new profile process"
or export existing profiles when clicking on one.

Behind the scenes this uses the new copyFile() method
to do the task.
