Improve compatibility with MT 5 "minetest_game"
This commit adds the following items: 1. The MT 5 API function "get_biome_name". 2. Stubs for the following four MT 5 API functions: set_clouds get_clouds set_formspec_prepend get_formspec_prepend The stubs are non-functional, but allow "minetest_game" to load. Additional work will be needed. 3. The "formspec_version" field that "minetest_game" now expects to find in the player information data.

The old engine build procedure still works, but it’s recommended that the build kits be used instead.
The build kits include source code and build scripts for gcc, g++, Irrlicht, LuaJit, SQLite3, and other packages. In some cases, the copies provided offer performance or feature improvements.
6.1. The old “buildbot” code is obsolete and has been removed. Use the build kits instead.
6.2. Due to work on 100s of commits, “doc/lua_api.txt” is out of sync. It’s useful as a rough guide, but parts related to newer commits need revisions.
