Openrepos backend system changed a little

Now the "Application" is some kind of bundle, where you describe application, add screenshots (some other content fields will be added later).
I called it a "bundle", because now you will be able to create platform dependent or source packages, and attach them to main "Application bundle".

So if your application supports several platforms, you should create 1 application, add screenshots/etc, and create "harmattan package", "sailfishos package", "nemomobile package" and so on. All will be attached to application, and will be visible while browsing app details.

"Platform package" dont have any limit on uploaded files. You can attach as many packages to your application as you want: i.e. all platform specific versions of application in single "platform package", or separate by 1 binary version.

In future, platform package will also contain extra switches about specific platform version or details (like harmattan "PR 1.1", "1.2 "; or maemo "fremantle", "fremantle 1.2", "CSSU") so you will be able to setup compatibility modes Based on modes package will be held in different repos.
With source packages those switches allows you to select target platform, so buildbots will compile, and upload binary packages for you.

Currently only "Harmattan packages" are online. Issue with "Architecture: all" will be resolved in next backend update within a day.

"Nemomobile packages", "Sailfishos package" and "Source package" types will be added soon

cli tools should be released during weekend, if I do things in a right way
