iPad optimizations [draft]

[saerdnaer]

These are a few minimal changes to get a somewhat working UI when using mumble on an iOS tablet. Basically this allows to rotate the screen and, split view etc.

The source code itself already included some specific iPad switches, which were not used as the info.plist file had only a UIInterfaceOrientationPortrait entry in the UISupportedInterfaceOrientations array.

A proper solution would be probably a proper SplitViewController etc. – but this was the first time after 5 years that I last looked at ObjectiveC source... :-)

Demo:

If you want to test this on your own device, and have no Apple Developer Account:

• see https://ionicframework.com/blog/deploying-to-a-device-without-an-apple-developer-account/ how to configure XCode and setup your "Free Personal Team"
• checkout this branch
• change the app bundle id to something other e.g. tld.your-domain.Mumble
• set the build system to legacy, c.f. Cannot build the project due to invalid .pch file #131 (comment)
• allow apps signed with these provisioning profile in your iOS device's settings
