Negmas

-------------

- [Core][SingleText] Adding single-text negotiation using Veto protocol
- [Core][Utilities] correcting the implementation of is_better
- [Core][Negotiators] Adding several extra honest negotiators that map functionality from the utility function. These are directly usable in mediated protocols

- [Core][Utilities] Adding several comparison and ranking methods to ufuns
- [Core][Event] improving the notification system by adding add_handler, remove_handler, handlers method to provide moduler notification handling.

- Adding NoResponsesMixin to situated to simplify development of the simplest possible agent for new worlds

-------------

- time_limit is now set to inf instead of None to disable it
- improving handling of ultimatum avoidance
- a round of SAO now is a real round in the sense of Reyhan et al. instead of a single counteroffer
- improved handling of NO_RESPONSE option for SAO
- updates to help with generalizing tournaments
- updating dependencies to latest versions
- Bump notebook from 5.7.4 to 5.7.8 in /docs
