Since minetest has no mobs within the core anymore, I suppose these
settings and code should go. Any mod that uses `minetest.setting_getbool`
will work with no problem since the default return value is `false`.

Config settings:
profiling = true/false (gather statistics)
detailed_profiling = true/false (break mod times to callbacks)

Chat commands:
save_mod_profile saves current statistics in debug.txt and shows on console (on default loglevel)

I love that setting. Why is it not in this file already?

Add TTL to item entities.

Add (experimental) support for topbottom as well as sidebyside 3d mode

Minor coding style fixes

Add support for (configurable) multiline hotbar
Improved screensize handling
Add userdefined gui scale by BlockMen

Parallax mapping with slope information.
Overriding normal maps.

Remove flagmask field from set_mapgen_params table
Add small bits of needed documentation

The commit didn't work because the blocks weren't loaded yet.

This reverts commit 22dbbf0a.
