Add InAppSettingsKit to xcodeproj and compile it with disabled ARC to avoid patches against upstream

additionally, add a header to collect the string constants used to provide the settings within the app

http file downloader: add a proper class taking care of this and use the circular progress indicator for visualization in the popover

menu: get rid of the http server info button and show the address to upload stuff directly in a label

proper design still to do

UI is iPhone only for now and due to lack of a preferences screen, there is no way to actually set the passcode

this solves some drawing issues, is a lot nicer to look at and edit and adds support for the linear progress indicator

Usage depends on future patches against libvlc
