Get rid of the system-specific updatelocales.sh and introduce an
updatepo cmake rule. po files are also updated before creating the mo
files, and we now keep the .pot file (in the po/en directory). To
stabilize the po file creation, file contents are sorted by source
filename.

Update po files in the process.

The po file should not be named c55 if we're in ∆. But since it is not
exposed at installation time, we don't actually need its name to be
based on the project name at all, so just call it minetest.po

This unbreaks the Windows build which would otherwise have problems at
the jthread level.

german translation file
and bashscript to update translations

New map generator added (and SQLite, messed up the commits at that time...) (import from temporary git repo)

Moved some mapnode content stuff from mapnode.{h,cpp} and digging property stuff from material.cpp to content_mapnode.{h,cpp}

Added an experimental "far view" thing. Doesn't work exactly like it should and not suitable for real use yet, and might never be.

configwriting/saving isn't complete and will break your config if you use fancy keys

added -Wno-unused-but-set-variable, which hides a new warning in gcc 4.6 which only slows down development with no effect on security or anything.
