server side changes to the snow docks addition and related fixes
Move starting brace to new line
Make fourth word of functions non-empty, to appease the current server
Canonicalize event label capitalization
run 'make maps' for client-data changes
Canonicalize case of items, which will soon be strict
Replace implict 0 in empty CSV fields with explicit 0
Kill some tabs
run 'make maps' for client-data changes.

update submodule pointer.
Allow specifying warps in terms of tiles instead of pixels

This interprets properties dest_tile_[xy] instead of dest_[xy].

Accepts both formats, but errors if there is a combination.
Switch supposed comments to actually use the comment prefix
Use canonical separator for mapflags
Fix some casing and spacing issues
Truncate item names to what the server actually sees

This is far from optimal, but the server was already doing it silently,
and the new server now rejects it.

Also make magic.conf use an item name, since previously it
was (correctly) rejecting the item name as nonexistent
and was using an ID instead.
Remove a couple of spaces and fix one case error in shops

When I rewrote the code for the shop parser,
it was much simpler to change these two NPCs than
try to preserve the exact parsing behavior.

The item case error, on the other hand, was just plain wrong.
Fix alignment and comment prefix in mob_db
