Description

Remove ncurses-based type of console, which is enabled only with -svgalib and -dedicated options. Since there no svgalib direct support (which is pretty old and too specific to Linux tech), it's better completely remove this code for simplicity and reducing external dependencies.

Removed -svgalib option as unused now.

Related Issues

Fixes #404.
