FileManager: Allow double-clicking applications again

Browse Source 
By adding a special LauncherType::Application we can still
get meta data for the application, but also know that we should
consider executing that binary as the default action. LaunchServer
will not do this for us, as it should probably not be allowed to
run arbitrary binaries that haven't been registered as handlers.
