Changes

Application:
- Option to hide symbols list to narrow the side bar
- Buttons to select previous/next symbol with shortcuts
- Custom cursor showing painting brush size

Functionality:
- Fix straight (Ctrl/Shift) lines paint to reset coordinate on mouse-up even if Ctrl/Shift is still held
- Command to make all blank symbols zero-width
- Alt-Scroll to change painting brush size
