* Removes redundant view_bobbing setting
Setting view_bobbing amount to 0 is now the only way to
turn view_bobbing on and off. Also fixed a bug where footstep
sounds would not play when view_bobbing was disabled.
After this, it should hopefully not record line numbers anymore,
so the diffs of updatepo.sh runs are smaller. Well, this is theory,
lets see how it will turn out to be in practice.
This solves two issues at once:
* CMake would delete po files during ‘make clean’ because it thought
they were autogenerated and not just managed
* the only gettext tools readily available in Windows are so old they
don't support options like --package-name
The change also moves minetest.pot down one level, so we don't need to
special case ‘en’ anymore.
The downside is of course that you need some sane POSIX shell to update
the po files.
