Visual enhancements
Here's a bunch of additions and changes to make Party Hat more fun and appealing! They include:
- New icon + accompanying symbolic
- Illustration for the main view
- Widgetry changes to accomodate the illustration
- Increased default window size
- Metadata changes: updated the description and made the summary follow the HIG
- String changes to clean up the language a bit
The last two points include making some strings more "professional", but I think the added visual stuff allows us to do that while keeping the app fun and relaxed
