Release 0.3 and 0.4

I wanted more experience with TypeScript and JavaScript and it was already something that I used a lot anyway so I decided to pick two of the seemingly simpler feature requests to work on. The two issues that I selected seemed related because they dealt with naming and file paths so it should hopefully somewhat reduce the amount of the code I need to understand.

Option to always disambiguate tab titles · Issue #69718 · Microsoft/vscode

This seems like the easier issue to tackle because it already works in a related circumstance. Extending that feature to also occur not only in the same tab group, but also across multiple tab groups seems entirely possible.

Unsaved tab labels should preview text instead of "Untitled-#" · Issue #37414 · Microsoft/vscode

Providing a default name for unsaved files was also a feature that I would also really like because it would make save all much more convenient.
