Converted player::wear_item to Allman style

For future commits.
Converted player::wear to Allman style

Just making it easier for me to modify.
Added non-interactive mode to player::wear

Now, we can use player::wear to "force" the player to wear stuff without
alerting him. Will be useful during character creation.
Made player::create armor equip more robust

Now, the player's profession might give him 10 pairs of pants, but he
can't wear them all at character creation.
