Fix dead ongen saplings due to biome_lib secession (#35)

* Replaced print with minetest.log in init.lua

* Added moretrees_ongen group to ongen saplings

* Added LBM and setting to enable it for non-functional ongen saplings due to biome_lib secession

* Changed LBM run_at_every_load to true

* Fixed luacheck warnings

* Using random interval for node timer, like in the on_generated timer interval

* Update init.lua

* Update node_defs.lua
