Arch Linux doesn't put it's ncursesw includes inside an ncursesw
directory.  This script ends up setting USE_CURSES as true, but
doesn't pick up any of the headers.

Instead of doing nothing at node_max.Y + 1 use 1-down
overgeneration for tunnel generation and noisemaps
Move some old unused code in mgv7 to end of file

It was caused by player not moving because fall was prevented, but their
velocity still increasing, causing fatal fall damage when world was
finally loaded. This commit fixes it by setting player velocity to zero
when the world around them is not loaded.

Fix warnings added by commit 01ae43c4

Fixes #3952

Also, rework the colorizing code to be more efficient.

Commit

c3b27975 "Move object nametags to camera"

has added a regression to still display
a shadow if their alpha got set to 0.

Additionally, fix misc. code style issues

Use a proper switch with breaks.

* Fix leak like behaviour if you load multiple schematics in a loop.

* Cleanup check in for, fixing theoretical out of bounds read if
	Schematic::deserializeFromMts reduced the number of elements
	in m_nodenames. A != check may need an overflow of the counter
	before it hits, if origsize is larger than m_nodenames.size().

* Fix function name passed to errorstream: it was wrong. Also use
	__FUNCTION__ instead of manually using the method name at other
	places in the function.

* Don't shadow the name member in the loop.

This fixes #3935, a regression from 0338c2eb.
An 'optimization' was performed where an index for the VoxelManip being
operated on was mistakenly used for bounds checking within the incorrect
VoxelArea, namely, the area wherein light should be spread.

Fix initialisation of variable 'disp'
Fix a few minor code style issues
Add independent X motion combining 2 prime frequencies

Writing an u8 to verbosestream writes a char, not it's numeric value.

This reverts commit 25da0594.

Commit

65c09a96 "Set acceleration only once in falling node"

has made the acceleration being set only once.
But this has introduced a regression.

Fix #3884.
