placement and transfer
* only_from_disk might not work anymore - check and fix it.
* Check the fixmes in the list above
* FIXME: Sneaking doesn't switch sneak node when moving sideways
* When sending blocks to the client, the server takes way too much
CPU time (20-30% for single player), find out what it is doing.
- Make a simple profiler
=== Making it more portable
* Some MSVC: std::sto* are defined without a namespace and collide
with the ones in utility.h
* On Kray's machine, the new find_library(XXF86VM_LIBRARY, Xxf86vm)
line doesn't find the library.
=== Stuff to do after release
=== Features
* Make an "environment metafile" to store at least time of day
* Move digging property stuff from material.{h,cpp} to mapnode.cpp...
- Or maybe move content_features to material.{h,cpp}?
