(both wooden and steel signs)
only streets mod's "bigpole" supported for now.
Model changes:
To make a sign support horizontal mounting, make a single "_onpole"
model, with two copies of the pole mount, one rotated by 90°. Make sure
the second copy appears has its own material entry, and that it is last
in the materials list in the exported .obj (`grep "g " file.obj` to
check).
When registered, signs_lib will set the "_onpole" and "_onpole_horiz"
tiles{} to reveal one mount or the other: entry 3 will expose the
vertical mount, entry 4 is the horizontal copy, with the opposite entry
being set to the "blank" image.
if available on a given sign. The sign must have a
"foo:bar_widefont" variant, with the horizontal scaling set
appropriately (about half of the normal value for the
narrow-font sign)
Add new corresponding API to anto-generate those signs where
desired; use this feature in default wood and steel signs
Any sign can now use a 15 or 31 px font, at any reasonable visual scale,
line width, number of lines, etc.
Split most signs off into a separate mod, basic_signs, which depends on
this one. Only the default minetest_game wood and steel signs remain in
signs_lib, completely redefined. The wall/yard/ceiling function for
wooden signs has been rewitten and moved to basic_signs, too.
signs_lib can now put almost any wall sign onto almost any kind of
posts/fence, as with most signs in my street_signs mod. Mods can add
their fences/posts to its "allowed" list, if needed (signs_lib tries to
detect most kinds of suitable fences, poles, posts, etc).
All signs affected by these changes are similar to what they've always
been, for continuity. The main difference is that they all use a 15px
font now, with a slightly larger scale, and the positions of some have
changed slightly.
Dropped the old "@KEYWORD" feature (but it could be re-added if it turns
out to be needed), and most of the old cruft like "|" for line breaks.
Created new wood and steel sign textures, derived from HDX.
See standard_signs.lua for examples of how the new API is used. The
"standard" text sizing/position/etc. variables are all at the top of
api.lua.
accessible by putting ^1 to ^8 (think "arrow number 1", etc) in your text
for narrow-width arrows (good for "wide font" highway signs), or ^a to ^h
for double-width arrows (good for all of the normal narrow-font signs).
in order, arrows 1 and "a" point up, 2/b points up-and-right, 3/c points
right, and so on, turning clockwise
Any other ^x pair just renders directly (no escape char, sorry)

Additionally, removed extra fonts. These will be distributed separately
to avoid bloating the repo too much.
