Allow Libraries to be Defined by Quests, Reusing Files of Interest.

[ekureina]

Right now, quests that contain files of interest are copied to quests by interested quest makers. Although I am not quite sure how to implement searching for libraries, libraries would be quests, or quests that only contain necessary components, that could be accessed by another quest. May help with #517.

Example API usage from scripts:

sol.main.define_lib(lib_name, lib_loc)

Then, when calling functions that use library data, add an optional library option to the end, defaulting to "self" which causes the engine to continue normal behavior. With this system, reusablility can be increased.

This might already be possible using sol.file. I am sure a lua library to be added to a quest could do the trick.

So you want several different quests to be able to use a common library? This is indeed the ideal way to do things.
Yes, this should already be possible with a simple require(), I think we don't even need sol.file. require() looks first in the quest directory, and then in usual Lua paths exactly like the standard require().
