Lots of good suggestions here

Most are quite hard to implement, I now went for that one:

allow changing the capacity via Lua. This way, the starting ship could have a bigger capacity than normal ships

I now gave the starting ship a capacity of 50 and load it with the following items (**untested**)

```
Atlanteans
log = 7,
granite = 5,
planks = 4,
spidercloth = 1,
iron = 2,
atlanteans_stonecutter = 1,
atlanteans_woodcutter = 1,
atlanteans_forester = 1,
atlanteans_geologist = 1,
atlanteans_miner = 3,
atlanteans_smelter = 1,
atlanteans_toolsmith = 1,
atlanteans_baker = 1,
atlanteans_smoker = 1,
atlanteans_fisher = 1,
atlanteans_soldier = 1,
Barbarians
log = 7,
granite = 2,
blackwood = 2,
grout = 2,
iron = 2,
barbarians_stonemason = 1,
barbarians_lumberjack = 1,
barbarians_ranger = 1,
barbarians_gardener = 1,
barbarians_geologist = 1,
barbarians_miner = 2,
barbarians_smelter = 1,
barbarians_blacksmith = 1,
barbarians_innkeeper = 1,
barbarians_fisher = 1,
barbarians_soldier = 1,
Empire
log = 6,
granite = 3,
planks = 4,
marble = 4,
iron = 2,
empire_stonemason = 1,
empire_lumberjack = 1,
empire_forester = 1,
empire_geologist = 1,
empire_miner = 2,
empire_smelter = 1,
empire_toolsmith = 1,
empire_innkeeper = 1,
empire_fisher = 1,
empire_soldier = 1,
Frisians
log = 6,
granite = 2,
brick = 7,
reed = 6,
iron = 2,
frisians_stonemason = 1,
frisians_woodcutter = 1,
frisians_forester = 1,
frisians_brickmaker = 1,
frisians_reed_farmer = 1,
frisians_geologist = 1,
frisians_miner = 2,
frisians_smelter = 1,
frisians_blacksmith = 1,
frisians_smoker = 1,
frisians_fisher = 1,
frisians_soldier = 1,
```

plus the port buildcost and a builder. Just a few basic building materials, essential workers for building supply and a simple mining infrastructure, some iron for the first tools, and one soldier for expansion.

I´d like to keep the needed total capacity on the ship <= 50.

Improvement suggestions are very welcome
