A small teaser (rcov 0.5.0)

As usual, there are some improvements in the heuristics (many multi-line quoted strings work now), a couple additional features, more polishing of the existing ones and a bunch of bugfixes. I also managed to automate the generation of RubyGems packages (including a cross-compiled, binary one for win32).
