- Added "Browse Captures" button.
- Improved the palette generation step by using a different oct tree implementation. This results in better colours in the final output. Less washed out. Seems faster too.
- Will now fall back to writing output to ~/Pictures if the install location is not writable.
- [Windows] Fixed capturing on 2nd monitor.
- [Windows] Moved default build to 64 bit.
