Some more tweaks in preperation for a submod update.

Minor tweaks to make patching the mod easier.

Updated the Vanilla Traits Expanded patch, pawns with the Prude trait will now only do lovin' with their partners.
Re-implemented the lovin' afterglow thought from vanilla.
Applied the lovin' cooldown fix to mechanoid lovin' as well.

Most lovin' functions were moved to their own helper functions. Although the mod was still super flexible before, modders can now tweak *everything* about lovin' without having to make complex Harmony transplier patches.

Implemented the aforementioned fix for mechanoid lovin' as well.

This will be the last update for the 1.5 version of the mod.

Implemented a potential fix for the notorious 'pawns getting stuck while doing a lovin' job' bug.

Implemented a new job giver for intimacy. Pawns that have low intimacy and the means to solve that will now actually seek some intimacy. This comes right after recreation, priority wise.
Nudism-related behavior changes now extend to pawns that believe in nudity as well.
Added a minimum seduction chance required for seduction attempts to happen at all. This prevents hopeless romantics from hitting on pawns they have no chance of seducing. Defaults to 20% but can be configured in the mod's settings.
You can now tweak how often seduction interactions happen with mod settings.

Pawns will now fail the lovin job if the pawn has not been moving for five seconds.

Reduced the commonality of recreation-based seduction attempts.
Pawns that are already lovin' are now ineligible for seduction attempts.
The regular 'Physical Love: Free' precept no longer increases the commonality of lovin'. The 'Physical Love: Free and Approved' precept still does, however.
Big cleanup of the backend. Some helper functions are now a lot more flexible. Some formerly repeating functions (like the lovin' spot finder function, which I had to maintain two slightly different versions of) have been rewritten and moved to the new utilities class.

Hotfix.

Pawns that believe in partner only/partner only if commited physical love can now share beds. Keep in mind that pawns not in a relationship will still get the 'sharing bed' mood debuff if they're forced to sleep together.

Fixed a potential error that could happen if a pawn's current job somehow returned null.

Pawns that are attending any ritual, ceremony, speech or wedding event will no longer try to initiate lovin.
Pawns that are doing any firefighting job will no longer try to initiate lovin.
Improved lovin' spot finding logic. This should fix rare instances where the picked spot would cause the involved pawns to get stuck due to having impassable/pass through only furniture there.
