fixed problems with iOS7 UDIDs

the iOS app will now also send it’s iOS Version to the server app. If
the server app detects >= iOS7 it will show all apps because it cannot
relay on the UDID anymore (because the UDID is not correct, no matter
if we currently use OpenUDID)
https Server

iOS 7.1 requires https for the plist and ipa links.
See:

esnt-work-on-ios-7-1/

I changed the server so it acts as a https server.

However there is still a problem in getting the iOS device to accept
your self signed certificates.
But this has nothing to do with the app (see the above link for
possible solutions)
