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
