The console has gained these escape codes: - Set color to any of 256 entries in the palette. - Set color to any 24-bit RGB value. - Inverse mode. - Bold mode. - Underline mode. - Move cursor to line N. - \a is now ignored. The effectively unused ATTR_CHAR has been removed. Parsing of escape codes has been improved. The graphical palette has been changed to the tango colors, which makes Sortix look a bit differently. Some user-space programs have been changed to use different colors that look better under the new palette. Remove const from methods that weren't really const and remove mutable keyword workaround.
