Added Body to the list of mutable parameters, added an escapeString for when a body parameter is changed and to make sure there's no warnings when a body parameter is logged
Merge branch 'rel-v6r12' of github.com:DIRACGrid/DIRAC into HEAD
Added a fix to the helper method __updateTransformationParameter which will update the body field without surrounding the string in an extra set of quotation marks
Merge pull request #2031 from SimonBidwell/fixTSBody
