Patch Notes: Crew at the Exchange

Buy and sell crew at any port

A crewed ship lying at a port's quay now lists Crew first on the shipwright's Exchange tab. Sign men on to her, or sign them off for gold: Buy 1, Buy 10, Sell 1, Sell 10.
Every port has sailors to spare (cheap), is short of them (dear), or neither, and its prices drift by the day like any trade good's. Every isle of the Veil is short of sailors.
Buy cheap where men are plentiful, sell dear where they're scarce. A man never sells for as much as the shipwright charges to hire one.
The row shows her crew aboard against her full crew, and a greyed Sell says why.

Selling never takes her last man, never takes a hand in your shore party, and always leaves one named hand aboard beside them.
When men leave, the least valuable go first: plain deckhands before anyone holding a post, a crew-hall recruit after the ship's own hands, her First Mate last of all. The note names everyone who leaves and everyone who joins.
A ship that came into the realm through customs can't sell her crew, and a booked passage's crew belong to her master.
Not during a fight. Crew is never an item: it can't go into packs, shops, stalls, the market or trades.

The crew row, its notes and its refusals are translated into every language, with gold in the language's own number format.
Fixes the failed deploy from #1195 (spells meeting outdoor ground).

Spells cast at the ground outdoors now strike it. A Fireball aimed at the grass bursts there, and a bolt fired into a hillside stops on the hill instead of flying on underground. Enemies' spells do the same.
A Fireball that bursts at your own feet outdoors now catches you in its blast, as it always has in dungeons.
Trees, rocks, crates and other cover now stop spells outdoors and inside buildings, as they already did in dungeons.
A spell's sparks and shockwave now land on the ground where it struck, slopes included.
Resurrect finds a fallen party member when you aim at the ground beside them outdoors.
Spells you give a party member or companion no longer pass through hills, and area blasts no longer reach over a hilltop.

An enemy caster behind a ridge now moves for a clear shot instead of spending its spell on the hill.
