Follows 34b1920e7b.
JSON functions and ToString are movec to their own headers.
Also clean out a few PersistentRooted usage to use the 2-phase init to
clean up scriptInterface usage.
With these functions split off, we can finally clean out headers and
remove ScriptInterface.h from most of them, in favour of smaller and
more precise headers.
Take the opportunity to clarify some comments regarding Mutability.
