jsoncpp deprecated function change

[fuzzard]

Same deal as the others. Changes deprecated function to charreader

Not runtime tested, but based on pvr.hdhomerun changes that have been.

Rebase required. I've been including this in my builds for weeks so should be ok to merge once rebased.

Rebased, same as the others, need some other good samaritan to come by and merge
