Cleaned a few messages up after pool naming feature.
--rawintensity option, by request of Dead2.
This setting allows to set the GPU intensity value directly without any modifiers, it does not
get any more raw than this! Look at the xintensity description raw for examples of regular
intensity values. You can also set this value through the ncurses interface by pressing:
G -> A -> select device id -> enter value.

Minor xintensity code cleanup as well.

Conflicts:
	driver-opencl.c
	miner.h
	sgminer.c
tui: display line getting off-screen on narrow terminals.
