jmoiron plays the blues

bb964393 to cm update documentation on show command to make it clearer
677ef45b to cm README in markdown looks ugly, back to plain text
5613834d to mandira reference implementation is better than alpha quality
d89d6ee3 to gokogiri change build paths to jmoiron/gokogiri, fix some build problems referencing non-existent functions in libxml2, two html tests failing related to the 'Accestor' function whose purpose I don't quite understand yet
cef1c06e to gokogiri update/rename README to also provide some information about the branch
