Better player damage prevention when falling on unloaded blocks, not involving getting stuck in there.

Switch more stuff to use the logging thing and fix segfault on player leave from server as introduced in a previous switch-to-logging commit

strict_protocol_version_checking setting; PROTOCOL_VERSION in clientserver.h; clean up defaultsettings.cpp and minetest.conf.example

Fix single-frame lag in camera yaw/pitch, tune view bobbing and add wielded tool movement when walking and tweak stuff a bit
