Removed outdated comments and unused constant RE_INTENSIVE

Replace a quint8 flag type with a uniform RenditionFlag
typedef (now quint16) in preparation for additional flags.

Add faint intensity support (SGR 2)

Four changes implementing faint intensity:
a) A new rendition flag RE_FAINT
b) Vt102Emulation to actually render text with
   a different color
c) ColorScheme support for "faint" colors
d) ColorSchemeEditor support

ColorScheme updates for faint intensities


Add strikeout support (SGR 9)


Add conceal support (SGR 8)


Add overline support (SGR 53)


Use normal intensity color by default

Incorporate comment by Martin Sandsmark handling
the situation where a color scheme fails to
define particular color.

I have been running this patchset for the last several months without issue.
