Formula for Omega (roguelike)

The class roguelike game.
Pathname can now identify -src versions, remove version from Omega.
Update usage of libexec for roguelikes.

Since "libexec" folders under the Cellar are already private per
formula, there's no reason to create an additional folder underneath
for namespacing.

Removed the extra folder level from these formulas.
s/require 'brewkit'/require 'formula'/g

brewkit.rb changes ENV destructively, so lets not do that everytime a formula
is required. Now it's possible for other tools to require a formula
description without worrying about side-effects.
Color Code

ColorCode is a free advanced MasterMind clone with lots of different game variants,
from the very easy up to really challenging ones.
Merge branch 'F-zsync' of git://arthur.barton.de/homebrew-alex
Use more inreplace features.

Update formulas to make more idiomatic use of "inreplace", including
its new ability to take a list of files to act on.
Formula for Net-Nuclear 4.
New formula cheops

CHEOPS (CHEss OPponent Simulator) is a fully-functional chess program capable of
human-vs-human, human-vs-computer, and computer-vs-computer play. It uses a
64-square linear array board representation. The game tree search is alpha–beta,
and the static evaluation function considers material, mobility, and motif features.
Adds New Formaula: avanor

    Avanor is a (not so) quick-growing roguelike game with easy
    ADOM-like user interface

New Formula: ski

    Terminal based game. Imagine you are skiing down an infinite slope,
    facing such hazards as trees, ice, bare ground, and the man-eating
    Yeti! Unfortunately, you have put your jet-powered skis on
    backwards, so you can't see ahead where you are going; only behind
    where you have been. However, you can turn to either side, jump or
    hop through the air, teleport through hyperspace, launch nuclear
    ICBMs, and cast spells to call the Fire Demon. And since the hazards
    occur in patches, you can skillfully outmaneuver them. A fun and
    very silly game that proves you don't need fancy graphical user
    interfaces to have a good time.

color-code 0.7.2

This is a version update for color-code, a Qt based board game,
akin to Mastermind, where you place colored tiles.  This was
compiled against Qt-4.7.4 and works very well on a 10.6.8
system running in 64bit.  Sometimes you come across an app that
builds so cleanly and has such a polished interface that it
makes you chuckle.  It could be the devs own a Mac.  Anyway,
here it is.
Closes #7997.

net-nuclear: fix quoting
cheops: style update
Shore up a number of shell quoting issues

When interpolating in strings passed to Formula#system, it should be
done in such a way that if any interpolated variables contain spaces,
they are either (a) passed as part of a list or (b) protected by quotes
if they are part of a long string (which is subject to shell expansion).
Otherwise, they will be split on the space when expanded by the shell
and passed as multiple arguments to whatever process is being executed.
