This commit is a preparation for the configuration file parser. The `int attr_*` variables have been moved into a separate struct. Members of that struct are alphabetically ordered, so an attribute can later be accessed by its name. Added `int get_color_pair(short fg, short bg)` for returning or creating a color pair number. Added call to `use_default_colors()` for enabling access to the terminal's default color (-1). Signed-off-by: Benjamin Abendroth <braph93@gmx.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
