[Feature] Encapsulate config logic (#1338)

* Define core/builtins, streamline status_color interface

* Encapsulate configuration in its own module

* Add fallback to lv-config.lua

* Rectify settings loading order to allow overriding vim options

* Move default-config into config/ module

* replace uv.fs_stat with utils.is_file
