New Features
- UI glow-up: Colors are more consistent, and themes set the styling for the entire app ([81](https://github.com/tconbeer/harlequin/issues/81)). Try `harlequin -t zenburn` or `harlequin -t one-dark` for a new look.
- Harlequin's query editor now supports more key bindings: <kbd>ctrl+z</kbd> and <kbd>ctrl+y</kbd> to undo/redo, and <kbd>shift+delete</kbd> to delete an entire line.
Fixes
- It is now easier to focus on the current editor buffer, instead of the tabs above it.
