Update generic_multi_select
Changes: - Add useful checks from `generic_select` - Sorting is now disabled by default (As many lists are already sorted) - Some checks have been changed (This includes unnecessary checks with `len()`, etc.) - Removed x, y from `print_large_list` as they aren't used in code - Added check for string to strip it without getting `AttributeError` - Switched to RequirementError handling as in `generic_select` - Added a log when the default option is selected with unselected options by the user - Added break when adding default option to empty list (See comments for more info) - Added support for selecting option by name
