Fix fg/bg texture setting in register_furnace

See merge request VanessaE/homedecor_modpack!7

If a custom fire_bg texture had been provided (not currently done
within the modpack itself), fire_fg would have been set to that instead
of the provided fire_fg or default.

Use API to replace beer mug

Closes #18

so that the spool of filament can be colorized.

Mods overriding minetest.do_item_eat can ensure that an empty glass
is given only if the item was actually used.

Fixes #18.

make sure player_api and 3d_armor load before wardrobe

(all still pointed to old node names)

make right-click handler work properly for plain "on"/"off" items

if mesecons, put "off" rope lights in creative inv, and drop them as "off" as
well.  else, put "on" in creative inv and drop "on"

allow right-click on rope lights only if no mesecons

also cache minetest.get_modpath("mesecons")

also remove "closed" curtain from creative inv
change recipe to give the "open" one

should fix #17 ?

bumped LBM version

replaced all "xz" and "toponly" with "alldir"
made on-floor rope lights use "alldir"

for backward compat, they'll resond to the usual strings, too:

"off" -> 0
"min" -> 3
"med" -> 7
"hi"  -> 11
"max"/"on" -> 14

all dimmable nodes have been renamed to bear the light value in their
names, and aliased.

the non-dimmable lights still respond as before
("off" or n < 4; "on" or n > 3)

to avoid confusion
