Removes "save_player_data()"

As discussed in #9574.

Restoring a graveyarded file retains the map changes (broken window
through which a Hulk punched my Fragile testchar) and corpse, but no
Hulk.

debugmsg to DebugLog for "lua replaces iuse"

Because we don't want to be bitching at the player when this happens,
but it might be useful information. Closes #9675.
Item_factory: clear iuse function list upon reset.

Rename Item_factory::reset to clear(),
Call clear() from the destructor (like before), and from the new reset function,
but also (re-)initialize the object after clearing it from within reset.

This means reset clears and reinitalizes the object.

game.cpp: DynamicDataLoader::unload_data calls reset in the Item_factory, which calls init, and also init_old, so init_old must not be called again from game.cpp.
This also means that init_old can be made private as it is not used outside of Item_factory.
Move lua iuse functions into the preload.lua file

To make them available before the iuse function get used when loading the item definitions.

Also added export of custom_iodine, as it was declared but not exported to the game.
Rotate duplex house, fix bathroom.
Rephrase jumper cable to say it "shares" power.

Because, according to @Jiamil, saying it "transfers" power is
irritating.
Replaces Detective's S&W 610 with an L39-45.

Police departments in the real world had already abandoned revolvers by
the turn of the century. A 20th century revolver doesn't make much sense
for a 2040s detective.

Giving the Detective profession what is basically an upgrade of the Cop
profession's M1911 seems more appropriate. Still, this slightly tones
down the Detective's pistol skill to compensate for the nicer gun.
Necropolis mapgen -> general mapgen. Part 1.
Replaces Cop's M1911 with a USP 45.

What police department would ever issue a century-old sidearm? The USP
is a far more sensible choice for beat cops.
