Update pager colors, tweak pager.cpp

Browse source 
Adds a color reset thing, to ensure fish tries to use hard colors during
testing.

Also, work on a discrepancy (not introduced by my changes, afaik) when
with some combinations of color settings, and usage of --bold, caused super
flakey color paninting in the pager. Downwards movements that trigger
scrolling vs. upwards movement in the pager would only apply bold to
selections when moving upwards. The bold state of the command completions in
the pager was flipping flops on and off, depending on if there is a description
on the preceding line.

Implement a lame fix by reseting the color to normal and applying a
different style on the rightmost ')' which seems to be what was influencing it.

Makes fish use terminfo for coloring the newline glich char.
