Revert "Move to cjson and drop pyjson and simplejson"

This reverts commit ee4535c98ae74347e7072909d49dcf8a5e16ca7b.

cjson has a big bug dealing with slashes, this is a significant
long-term bug and upstream has not been responsive other than
acknowledging it. This bug breaks journal entry bundles.
http://dev.sugarlabs.org/ticket/1553

Thanks to Martin Langhoff for identifying and researching this issue
