Don't reward digging close w/ drill rocket. Doesn't offer much benefit. Reduce final bonus slightly to avoid using drill like bazooka. Better would be AI doing this for all weps based on count. Make main drill loop a little more efficient.

# - Try to find the Glasgow Haskell Compiler executable
# Once done this will define
#
#  GHC_FOUND       - system has GHC
#  GHC_VERSION     - GHC version
#  GHC_EXECUTABLE  - GHC executable
