json-glib: update to 0.14.2

[ryandesign (Ryan Carsten Schmidt)]

Here is a patch attempting to update json-glib to 0.14.2. It doesn't build for me though:

  GISCAN Json-1.0.gir

r87905 addressed the build failure reported, but 0.12.4 had other failures, so r87907 updates json-glib to the latest version.
