Small update: bug fixes

Fixed:

1. Switching from Text tool to another tool can lead to shift, alt and ctrl not being detected.

2. Making changes to the font size using the keyboard can cause unexpected changes to the text content.

3. Animation onion skin is not working after the layer blending mode update.

4. When you make a duplicate of a tab and then click save, instead of prompting for a filename it just overwrites the original file.
