Use API to replace beer mug

Closes #18

See merge request VanessaE/homedecor_modpack!5

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

doors:wood_glass_{oak,white,mahogany}_{a,b} --> doors:homedecor_french_{oak,white,mahogany}_{a,b}
doors:woodglass2_{a,b}                      --> doors:homedecor_carolina_{a,b}
doors:bedroom_{a,b}                         --> doors:homedecor_basic_panel_{a,b}

All others:
doors:$foo_{a,b}                            --> doors:homedecor_$foo_{a,b}

make them mesecon/digiline controllable (on/off only, alldir rules)

also fix a couple of old texture references

merge table and standing lamps into the new code

of all the relevant lights, the plasma ball is the only one that remains
on/off-only, since dimmable doesn't make sense there.

That one, and any future lights that get the on/off-only treatment, will
use the previous on/off behavior, i.e. turn off with the messages "off"
or "low" or a number < 4, and turn on with "med", "hi", "max", "on" or
a number > 3

This alters the behavior of table/standing lamps - they will no longer
cycle brightnesses by right-click.  Like all other controllable lights,
they'll just toggle on/off.  If there's enough demand for it, I'll add
that feature back in at a later date.

allow non-dimmables to respond to "off", "low", "med", "hi", "max", "on"

number messages for dimmables:
0 turns the light off
1-3 sets it to "low"
4-7 sets it to "med"
8-11 sets it to "hi"
12+ sets it to "max" (i.e. full-on)

non-dimmables:
a number > 3 or the strings "med", "hi", "max", or "on" turn the light on
a number < 4 or the strings "off" and "low" turn the light off

digiline stuff to be more generic, and add various digilines connections
rules to complement mesecons rules.

Mesecons must be present to get the "wallmounted" rules for digilines nodes.
Without mesecons, nodes that want wall rules will get alldir rules instead.

Add mesecons support to table and standing lamps (off -> max -> off).

Add digilines support to all other lights that now support mesecons,
except rope lights, since they're a mesecon conductor.

(will approach that last one later)
