color wrapper

The "cwe" command was added. The "supermap"
definition instruction and the "CW_SUPERMAP"
environment variable check were added to change
the internal color format to a completely
different color format, such as HTML tags. The
"lborder", "rborder", "forcecolor", "print",
"noeol", and "proctitle" definition instructions
and "CW_LBORDER", "CW_RBORDER", and "CW_RANDOM"
environment variable checks were added. Automatic
proctitle support was added to improve process
listing appearance. Handling of user interrupts
(CTRL-C) was changed. Multiple bugs were fixed.

"!" and "@" were added to run programs as they are
placed in the cw definition file. The "ifexit",
"ifnexit", and "ifexit-else" definition
instructions were added to compare exit levels.
The "CW_CHK_NOCOLOR" and "CW_CHK_SETCODE"
environmental variable checks were added to run a
program or shell expression and check the exit
code to either disable or set to be used against
the "ifexit" definition instructions. The
"useifregex" definition instruction was added to
enable use of regex comparisons with the "ifarg"
and "ifos" definition instructions. Multiple bugs
in cwu were fixed.

Checks were added for the "CW_HEADER" and
"CW_FOOTER" environment variables, to set a header
or footer if there is not one specified in the
definition file. The "remap" definition
instruction and the "CW_REMAP" environment
variable check were added to remap colors to
special ANSI (code) colors or other internal
colors. The "clear" definition instruction and the
"CW_CLEAR" environmental variable check were
added, to clear the screen before the program
starts. The "nocolor" definition instruction was
added, to disable all coloring via a definition
file. Pre-made headers and footers were added.
Several bugs were fixed.

A bug that could cut off the last lines of long
output from programs that process faster than cw
was fixed. Passing of the exit value was added.
The "ifos", "ifnos", ifos-else" and "ifarg-else"
definition instructions were added for more
specific coloring situatons. The "nobackground"
definition instruction was added to disable
stopping the program (with ^Z). Support for
stopping the program while running (with ^Z) was
added. Support for Solaris and Cygwin was added.
The deprecated "OS=" argument used in conjunction
with "ifarg" was removed. The pre-made groups,
arp, mount, ping, lsof, ps, and df definition
files were added or revised.

The "regex" definition instruction was added. The
"usepty" definition instruction and the
"CW_USEPTY" environment variable check were added.
The "OS=" argument was added to be used with the
"ifarg"/"ifnarg" definition instructions. The
"CW_INVERT" environment variable check was added.
"env" was added to be used with the "path"
definition instruction to import the PATH
environment variable. An autoconf install
procedure was added. An infinite recursive bug
when using improper "path" definitions was fixed.
Fixed "colorcfg" for local install usage. The
"cwu" line-wrapping bug was fixed. Many definition
files were added or revised.
