Seperate signs API from signs definitions

[pyrollo]

That's a good idea to separate the sign api from the mod. At first, this mod was just a use case demo for display lib.

I'm thinking about names. It would be better to have homogeneous names for mods, So as we have display_lib and font_lib, signs_api shoud be signs_lib but it would conflict with minetest-mods/signs_lib.

I see tree possibilities :

• display_lib / font_lib / sign_lib (but sign_lib is very close to signs_lib)

• display_api / font_api / signs_api (but AFAIK, it's more usual to use _lib ending)

• Merge signs api in font_lib

And for the remaining, signs mod, I'll rename it signs_basic or something like that (this implies use of aliases for compatibility reasons).

I'm still thinking about that. What is your opion ?

After thinking about this, I actually prefer display_api / font_api / signs_api.

In my opinion, the first option would cause too much confusion with the other signs mod.

The third option would solve the name problem, but I prefer to separate font_lib from signs_api. Both APIs are designed for different usages. font_lib is a more general approach, while signs_api is very specialized.

Please tell me your choice, when you have decided what option you prefer, then I'll update this PR accordingly.

Thanks!

Let's go for display_api / font_api / signs_api. I'll change the signs mod name the.next time I'll do significant things on it. Thank you :)

The PR is updated now.

Please test this before merging. This is a rather large change, and I cannot guarantee that I didn't overlook a mistake. However, I tested this briefly, and it seems to work.

Thanks!
