New welcome screen UI
The current welcome screen UI doesn't suit me very well, so I decided to design a new one. Pros of the new UI:
- it has a cohesive design and is visually separated from the rest of the view
- using QScrollArea as a basis avoids squeezing its contents and doesn't limit the minimum window size
- it's more compact and suitable for small screens
- it also displays saved sessions
