representation of non-APK files isn't great at the moment

I'm currently working on experimental support for iOS apps in fdroid server. Since I've got a test repository with .IPA apps up and running at the moment, I noticed that F-Droid client doesn't do a great job at presenting non-APK files.

Also for some reason on my phone (1.19.0-alpha0) install and uninstall buttons show up at the same time. Klicking the uninstall button makes an Activity? flick up and disappear instantly. (I really only see an animation but no content, because it disappears pretty quickly too) With no notice able effect

(If you'd like to test with my dev repo, I've posted the repo link to ffdw chat, just add /fdroid/repo to the url or use the link/qr code in the PWA ...)
