no issue
- With the changes in 79ca6c575c we removed old unused events
- The theme upload event is still used and needed to be put back
- Added the event emit right after the successful upload of the theme
- Renamed analytics events for more consistency
- We need to add the same event emitter to the v0.1 API as it's not deprecated
- emits a `theme.uploaded` event after the theme was successfully uploaded and saved
