Adding 256-color support. This requires a version of ncurses that supports ABI-6. Colors beyond the first eight are refered to by number. Perl now has the number of colors exposed to it by way of BarnOwl::getnumcolors() and also has a mechanism for undefining filters using BarnOwl::_remove_filter([filter-name]) You can't remove the 'all' filter or the current filter.
