Opens more positive and negative traits to non-custom species. (#15928)

* Allows other species to autohiss

Opens the autohiss traits to all species except for Tajara, Unathi and Zaddat who come with them by default.

* Opens more positive and negative traits to non-custom species.

Added access to various negative and positive traits for non-custom species, where it makes sense that there might be variations due to natural differences and body modifications. I have excluded specific species from accessing most of these where they are already meet those levels or would be buffed too much and lose their balanced flavour.
Whilst I realise there is a system in place to stop negatives making things stronger, I have excluded these species anyway so people don't accidentally waste points on them.

Specifically:
Positive traits:
Haste (excluding Unathi, BESK, Diona and Alraune due to their design. Tesh and Taj due to already having this buff).
Hardy and Hardy+ (excluding Tesh, Prommie and Protean to avoid balance. Alraune, Unathi and diona already have this).
High Endurance (excluding Tesh and BESK to avoid buffs, and Unathi who already have this).
Darksight and Darksight+ (excluding all those who already get to see in the dark)
Brute resist minor only (exlcuding Tesh for the buffs and those that already have this level of resistance).
Grit

Negatives:
Slow and Slow+ (excluding those that already move so slow)
Weakling and weakling+ (excluding BESK and tesh who are already this weak)
Low endurance and + (excluding besk for the first and tesh for both as they're already that weak)
Brute weakness minor, normal and major (excluding those that are weak to specific levels)
Neural Hypersensitivity

* Removes Haste

Removes haste from the options as requested.
