Geert Janssens 8d24252860 RptCleanup - Internalize guile-json module
This is in preparation of the final guile restructuring step:
install gnucash scm files directly in guile's default site module directory.
Internalizing json is done to prevent an install clash with a potentially
system installed guile-json module.
