Broke the sed expressions out of build.sh and put them their own documented sed script. This greatly improves readability and avoids build.sh getting messier. Broke the substitution command into two separate subs. The first just deletes comments, and the second collapses all whitespace into a single space. This too is easier to read, and catches a couple of edge cases that would result it not all whitespace being collapsed. The result may still have (one) leading and/or trailing space, which is acceptable.
