SDK Updater: UI polish

Fixes the following issues:
- Updater says it didnd't install addon and then install it
  (cause: UpdaterData was looking for an ArchiveInfo in a map of Archive)
- Added a label explaining the [*] in the dependency list.
- Added the originating site to the long description in the package chooser.
- Display downloading/installing comments in the result window.
- Fixed app name in dialog when tools are updated.
