adds help page

- urls are now auto-generated from android
  and no longer self-handled
- long-clicking a message starts decryption
  process, short clicking does nothing right
  now
- only first three messages are decrypted
  on app load, to improve performance
- fragment structure now inside a list view
  which makes the listview inside scrollable
  automatically
