Add icons for desktop applications and Apple App store.

- Add yapf style file for consistency of formatting
- Some minor changes and renaming
- Add template tag filters for checking conditions
- Move icons from img directory to icons directory

Currently the client listing is in both the SetupView and ServceView for ease of
development. Have to remove from ServiceView.
