Various fixes:
. Fix title of a section.
. Fix grammar in a few places.
. Always use <quote>...</quote> instead of <quote/.../ for quoting.
. Use an entity when referring to make(1) as a command.
. Remove the 'living dangerously' part until I find better words to

describe it, or someone comes up with a better way to describe all
the possible variables one can use while building world.
