Pregnancy support in engine is finished. Also I add texts about it to the characters descriptions.

But I just found a little logic issue, that I not think about before: birth process time handling.
Technicaly it's done, but what to do, if pregnant character is a worker, but not in the walk mode, and player busy with other character? Or what to do, if character out of the base and out of control (in hospital after loss of the fight, for a sample)?

After quick thinking, I came up with this for now:

- If worker at the time of birth in a walking mode, there will be a special event, which begins natural birth chains of events.

- If worker is at base, player will have allert window with message with something like "<Name> waters is broke!" and can have something like 1-2 game hours to end current link and switch attention to the birthing character, to begin that chain of events.

- If worker can't be accessed (hospital, or other cases), or player just not give attention in time, birth will be completely offscreen, and only with note in the character's journal. May be there will be some penalty for player in this case. Not sure, for now.
