Remove 2 unused number tags in Construction Mode GUI These numbers are shown aside the power tag, but the numbers never change. They don't serve any purpose and are just visual clutter and annoying, since they partially overlap. They are probably a leftover from copying code over from other scripts. With this changeset, only the power and turn time are left visible, as it is supposed to.

# Determine the compiler to use for Pascal programs
# NOTE, a generator may set CMAKE_Pascal_COMPILER before
# loading this file to force a compiler.
# use environment variable Pascal first if defined by user, next use
# the cmake variable CMAKE_GENERATOR_PASCAL which can be defined by a generator
# as a default compiler

# NOTE: on Darwin cmake >= 2.8.11 until cmake <= 2.8.12.1 will add an incompatible
# -F flag to <FLAGS> so you won't be able to use those versions with this script
